Cipla has been awarded a public sector vaccine tender, reaffirming the company’s commitment to strengthening South Africa’s immunisation program through the equitable supply of high‑quality, affordable vaccines.
Cipla submitted bids across several critical paediatric and childhood immunisation categories, including Pneumococcal Conjugate Vaccine (PCV‑10), Rotavirus vaccine, Hepatitis B (Paediatric formulation). These vaccines play a vital role in preventing life‑threatening childhood illnesses and reducing the burden on healthcare systems.
CEO of Cipla Africa, Paul Miller, said: “This tender award marks an important milestone for Cipla as we continue to expand our vaccine footprint in support of national immunisation priorities. We can meaningfully contribute to comprehensive immunisation programmes and long‑term disease prevention efforts.
“Our participation across multiple vaccine categories demonstrates our commitment to addressing critical public health needs and strengthening health outcomes for children and communities.”
Cipla’s vaccine portfolio is underpinned by stringent quality standards and a focus on ensuring continuity of supply reliability. Cipla has a long history of partnering with the Department of Health to support equitable access to quality healthcare, including the supply of antiretrovirals and various vaccines.
Cipla South Africa focus will be ensuring reliability of supply, consistency, and responsible partnership with the public health sector, particularly in communities where access to healthcare remains uneven. CEO of Cipla Africa, Paul Miller, said: “This tender reaffirms our ongoing partnership with the state, as part of Cipla’s mission of ensuring access to quality, affordable healthcare.”
As part of our ethos of “Caring for Life”, we strongly believe in the importance of robust routine immunisation programmes that save lives, reduces inequality and delivery lasting benefits for society as a whole. In public health, progress often comes down to getting the basics right – ensuring vaccines are available, delivered on time, and reach every child who needs them.”
Participation in the Expanded Programme on Immunisation (EPI) aligns with Cipla’s broader mandate to support preventative healthcare and long‑term public health sustainability, said Miller.
Cipla South Africa continues to work closely with healthcare partners and has invested in initiatives to strengthen vaccines knowledge and reduce vaccine hesitancy. For more information about vaccines, visit https://medinformer.co.za/?s=vaccines

Researchers at Karolinska Institutet, in collaboration with colleagues at The Scripps Research Institute and Emory University, have developed a new vaccine strategy that has generated antibodies capable of neutralising highly divergent HIV variants. The study, published in the journal Nature, provides new insights into how the immune system can be guided towards a particularly protected part of the virus.
HIV mutates rapidly, making it difficult to develop an effective vaccine. One major challenge has been to stimulate the immune system to produce so‑called broadly neutralising antibodies that recognise parts of the virus shared by many HIV variants.
In the study, the researchers focused on a small structure located at the very top of the virus’s surface protein, known as the apex, which is important for the protein’s three-dimensional structure. The apex is similar across many HIV variants but is shielded by dense layers of sugar molecules, making such binding difficult to achieve.
“We developed a strategy in which specially designed HIV proteins were attached to tiny fat particles, known as liposomes. This enabled multiple copies of the virus’s surface protein to be presented to the immune system simultaneously, thereby strengthening the immune response”, says Mónika Ádori, researcher at Department of Microbiology, Tumor and Cell Biology, Karolinska Institutet.
The vaccine strategy was tested in an animal model in which macaques were immunised with liposomes linked to a selected HIV protein and then given booster doses in which the protein was gradually altered. The aim was to train the immune system to recognise features that are shared across different HIV variants.
Resembles antibodies that develop in humans
With this strategy, all vaccinated animals developed antibodies that neutralised a wide range of HIV variants. When the researchers analysed the antibodies in more detail, they found that they bind to the virus’s apex in a way similar to antibodies that sometimes develop in humans after long‑term HIV infection.
“The study shows that it is possible, through vaccination, to steer the immune system towards this specific part of the HIV surface protein,” says Gunilla Karlsson Hedestam, professor at the Department of Microbiology, Tumour and Cell Biology at Karolinska Institutet and a shared senior author of the study.
“This is an important step towards understanding how an HIV vaccine could be designed. Discussions are now underway about how the strategy could be taken forward into clinical studies,” she continues.
The study was funded by the US National Institutes of Health (NIH). The researchers report no conflicts of interest.

This African Vaccination WeekSanofi South Africareaffirms its commitment to vaccine awareness, access and public health partnerships to close the immunisation gap

Johannesburg, 20 April 2026 – Marked each year from 24 to 30 April, African Vaccination Week focuses on the need for equitable access to lifesaving vaccines across the continent.
It’s also a timely reminder that while vaccination remains one of the most effective tools in public health, gaps in coverage are a real concern, in South Africa and globally. UNICEF says immunisation prevents an estimated 4.4 million deaths every year,1 yet WHO reported that 14.3 million children worldwide missed out on all routine vaccines in 2024.2 Global coverage for the third dose of DTP-containing vaccine stood at 85% in 2024, while first-dose measles coverage was 84%.2
“Vaccination remains one of the smartest and most effective investments in public health,” says Jean-Baptiste Bregeon, Country Lead and Head of Vaccines, Sanofi South Africa. “Improving coverage is not only about having vaccines available. It’s about building trust, strengthening health systems, supporting healthcare workers and making sure people have the information they need to act. African Vaccination Week is a reminder that protecting lives takes sustained effort and strong partnerships, and Sanofi remains committed to playing its part in South Africa.”
In South Africa, the need is clear. The National Department of Health reported in 2024 that 80% of children in the country had received all their vaccinations by the age of one.3 That is progress, but it also means one in five children had missed one or more doses and was not fully protected. UNICEF South Africa has separately highlighted the urgency of reaching children who have missed routine immunisation entirely. There were 58,000 more zero dose children in 2024 and 278,000 without vaccination, leaving them vulnerable to vaccine preventable diseases.4 Measles vaccination coverage, for example, declined from 80% in 2023 to 76% in 2024.4
Recurring outbreaks of measles, cholera, polio and diphtheria have added pressure to the health system, while disruption to routine immunisation has left more children vulnerable to vaccine-preventable diseases and increased the risk of further outbreaks.5
This year’s campaign aims to intensify vaccination and surveillance activities in districts with high numbers of under-vaccinated and unvaccinated children. Vaccines included in South Africa’s national immunisation schedule are available free of charge at primary healthcare facilities.
Sanofi says its focus in South Africa over the next two to three years will be to continue supporting the Department of Health to improve vaccine coverage across the country, with a focus on access, availability, education and awareness.
“Improving vaccine uptake requires a practical, local approach that recognises the realities of South Africa’s healthcare system, including uneven coverage, pressure on frontline services, and the challenge of reaching communities across both urban and rural settings,” says Bregeon.
That’s why partnership matters, he adds. “Improving immunisation outcomes takes coordinated action across government, healthcare providers, communities and industry. Strong supply is important, but so is public confidence, clear communication and consistent follow-through at clinic level.”
This African Vaccination Week, Sanofi calls on all South Africans to ensure their vaccinations are up to date and encourages healthcare providers to continue championing immunisation as a cornerstone of preventive health.”
Two new vaccines to prevent tuberculosis (TB) are safe for use in adults and children, but they do not offer protection against all forms of TB, finds a large trial from India published by The BMJ.
TB remains a major global public health concern. In 2023, an estimated 10.8 million people worldwide were reported to have TB and the rate of new cases increased by 4.6% between 2020 and 2020, highlighting the growing scale of the problem. BCG is currently the only licensed vaccine against TB. Yet although it is effective against severe forms of TB in young children, it does not offer protection for adolescents and adults.
To address this gap, researchers in India conducted a large trial to evaluate whether two new TB vaccines (VPM1002 and Immuvac) can protect against all forms of tuberculosis (pulmonary and extrapulmonary), prevent latent (dormant) infection, and generate an immune response against the TB bacterium.
The study enrolled 12 717 household contacts (aged 6 years and older) of recently diagnosed TB patients across 18 sites in six Indian states between July 2019 and December 2020.
Participants were randomly allocated to receive a first dose of either VPM1002, Immuvac, or a placebo (4 239 in each group) and were followed up for 38 months. A second dose was administered to 11,829 participants one month later. A total of 12 295 participants (96.7% of those enrolled) completed 38 months of follow-up.
While neither vaccine offered general protection against TB or prevented latent TB infection, both demonstrated an ability to prevent the progression to active TB in those who developed latent TB.
The researchers found that although both vaccines did not show effectiveness against all TB and pulmonary TB (PTB), one of the vaccines, VPM1002 showed effectiveness (50.4%) against extrapulmonary TB (EPTB) across all age groups, including those aged 36-60 years (79.5%). These findings suggest a potentially significant public health benefit, because extrapulmonary TB, which affects organs beyond the lungs, is often associated with a higher risk of mortality than pulmonary TB.
A promising key finding was the protection seen against TB in children, whereby VPM1002 provided protection against all TB, PTB and EPTB in the 6 to under 14 year age group, while Immuvac provided protection against EPTB only in the 6 to under 10 year age group.
However, neither vaccine protected children and adults who were underweight. This suggests that nutritional support may be needed along with vaccination, especially for younger children, report the authors.
Both vaccines were found to be safe and induced an immune response.
The researchers acknowledge that the covid-19 pandemic affected the study, leading to the exclusion of some participants who missed the second dose and sometimes delayed follow-ups. Furthermore, the findings may not apply in other countries or ethnicities.
Nevertheless, this was a large, well-designed study that reflects a real world scenario because it included both children and adults, regardless of pre-existing conditions like diabetes and risk factors, as reported by authors. Further research on commonly targeted high-risk groups for TB could be undertaken, they conclude.

The only tuberculosis vaccine we have is a century old and offers only limited efficacy in children. With leading South African researchers involved in the pivotal clinical trials of three new tuberculosis vaccine candidates, we are on the verge of a major breakthrough, writes Associate Professor Angelique Kany Kany Luabeya.
My uncle died of abdominal TB a few days ago, after facing repeated challenges in getting an accurate diagnosis. For him, the treatment started much too late. To many in his community, my uncle was a respected teacher, a breadwinner, a pillar of support and strength.
In 2026, why are people still dying from a preventable disease that continues to cause unnecessary deaths and hardship?
Why we urgently need a new TB vaccine should be obvious. For the millions who are sick, and for families living with the catastrophic loss of a loved one, the need is painfully clear.
Prior to the emergence of the SARS-CoV-2 virus, TB was the world’s deadliest infectious disease, killing more than 1.5 million people every year. While COVID-19 has since shown an epidemic downturn, TB’s toll remains devastatingly high.
Globally, an estimated 2 billion people are infected with the Mycobacterium tuberculosis that causes TB in humans. In this state, also known as latent TB infection, they do not have TB symptoms and are non-infectious, but the bacteria remain dormant in their bodies. Of these people, about 5 to 10% will go on to develop active TB when their immune system is no longer able to contain the bacteria. This means that they now have TB disease, sometimes without noticeable symptoms, and risks passing it to others. This could be a family member, a friend, or a stranger who happens to be nearby.
TB bacteria have coexisted with humans for millions of years. There is a cure, but treatment alone is not enough to stop transmission. TB mostly affects countries with limited resources because patients struggle to access care or are unable to complete treatment due to side effects or a lack of food to support the rigorous regimen of drugs they must take to cure them. In addition, the rise of multidrug-resistant tuberculosis is now fueling a global health crisis.
In South Africa, recent data from the World Health Organization’s (WHO) Global TB Report indicate progress, with a 57% reduction in new TB cases since 2015. However, TB mortality is still high and is concentrated mainly in poor and vulnerable communities. According to the WHO, TB still claims over 50 000 lives in South Africa every year. The burden is also unevenly distributed, with some geographic areas affected more than others.
A vaccine which prevents TB
Our hopes are now pinned on developing an efficacious vaccine which prevents people from developing TB disease. WHO modelling suggests that a vaccine which prevents most people with latent TB infection from progressing to active disease would have the most rapid impact on the epidemic in high‑burden countries.
The most urgent priorities for protection would be people living with HIV, healthcare workers at risk of workplace exposure, adolescents and young adults who are driving transmission, as well as those with comorbidities such as diabetes that increase their risk of TB diseases and negatively affect treatment outcomes.
The COVID-19 pandemic proved that when human survival is threatened, the scientific community can respond with breathtaking speed, developing multiple effective vaccines in under a year. Sadly, the urgency and resources allocated to finding an effective TB vaccine do not match the scale of its devastation.
For more than a century (since 1921), we have had only one licensed TB jab, which is the bacillus Calmette-Guérin (BCG) vaccine that is given at birth. Despite its limitations in preventing TB that infects the lungs – the main route of transmission – BCG remains a critical tool because it protects millions of babies from more serious forms of TB that can spread through the blood to the brain. But, clearly, the BCG vaccine is not enough.
Hope is on the horizon though, with several novel TB vaccines now in late-stage clinical trials. New vaccines or drugs are evaluated clinically in humans in steps, or phases, for safety, immunogenicity, and efficacy.
The most advanced is M72/AS01E (M72 for short), which is an adjuvanted subunit vaccine under development by the Gates Medical Research Institute and GlaxoSmithKline. In a phase 2 trial, this vaccine showed close to 50% efficacy in preventing TB disease in TB-infected people—the first time a vaccine has achieved this level of efficacy. A pivotal phase 3 trial of this vaccine has now completed enrolment of 20 000 volunteers, including 13 000 people in South Africa, with results expected in 2028. Developers typically apply for registration with regulatory authorities after successful phase 3 trials – so this study is the last big hurdle for this vaccine.
Another promising candidate is the MTBVAC vaccine, a live, whole, attenuated Mycobacterium tuberculosis vaccine developed by Biofabri, in partnership with the University of Zaragoza and sponsored by the International AIDS Vaccine Initiative. It is in a multi-country phase 2b trial in adults and adolescents and a phase 3 trial in newborns, including in South Africa.
BioNTech’s mRNA TB vaccine is also being evaluated in a phase 2a study in South Africa. Funded by BioNTech, this vaccine candidate harnesses mRNA technology, which has proved successful in the COVID-19 response.
Paving the way for acceptance and use
South African researchers are at the forefront of these TB vaccine efforts. Our strengths lie in our robust clinical trial capacity, world-class institutions, commitment to equitable solutions, and regulatory expertise, all of which help accelerate vaccine licensure. As a global policy leader, South Africa co-chairs the Finance and Access Working Group at the WHO TB Vaccine Accelerator Council, advocating for fair distribution and sustainable financing, and has recently co-hosted a vaccine preparedness workshop to position the country for the emergence of late-stage TB vaccines.
But the most important aspect to consider is the vaccine’s acceptability and uptake by a myriad of population groups at risk of TB. We learned from COVID-19 how misinformation can devastate vaccine uptake, leading to unnecessary morbidity and mortality. Confidence in new TB vaccines must be built to maximise impact. The context may be different—TB is an old, well-known enemy that affects people close to us. By involving South African communities in the early stages of vaccine trials, we can ensure their priorities are part of the development agenda.
While we continue to improve TB diagnosis and treatment, the hunt for an effective vaccine continues. After a century of fighting TB with only one vaccine and several antibiotics, we might be on the verge of a breakthrough that could finally shift the trajectory of this ancient and deadly disease.

In South Africa, where the burden of HIV remains high, women living with HIV face a disproportionately increased risk of cervical cancer, around six times higher than women without HIV. This heightened risk is driven by persistent infection with high‑risk strains of human papillomavirus (HPV). In settings where access to HPV vaccination, cervical screening and treatment is uneven, the impact on women’s health and lives is profound.
New research published in The Lancet Global Health provides the first population‑level evidence globally that a national HPV vaccination programme can be highly effective in a high HIV‑prevalence setting. The study was led by researchers from Wits RHI at the University of the Witwatersrand in partnership with the Kirby Institute (University of New South Wales).
The study evaluated South Africa’s free, school‑based national HPV vaccination programme, introduced in 2014, which offers HPV vaccination to girls in Grade 4 (aged nine years and older) attending public schools across the country. Crucially, the research assessed vaccine impact among adolescent girls and young women both living with HIV and without HIV, reflecting the realities of South Africa’s dual HIV and cervical cancer burden.
Until now, most evidence on HPV vaccine effectiveness in people living with HIV has come from studies where vaccination occurred after HIV infection, often after exposure to HPV and in the presence of immune suppression. This South African study, led by Professor Sinead Delany-Moretlwe at Wits RHI, Director of Research, is the first to demonstrate the real‑world impact of vaccination delivered early, before most girls are exposed to HPV, within a national public‑health programme in a high HIV‑burden context.
The findings show that the HPV vaccine provides excellent protection, including among girls living with HIV. Researchers observed substantial reductions in vaccine‑type HPV infections, demonstrating that high‑coverage HPV vaccination programmes can deliver strong population‑level benefits, even in settings with widespread HIV.
“For the first time, we can demonstrate at a population level that HPV vaccination delivered early, through a national public programme, provides excellent protection in a high HIV‑prevalence setting. This is a major public‑health success for South Africa and sends a clear message globally: investing in early, school‑based HPV vaccination can dramatically reduce future cervical cancer risk, including among girls living with HIV,” said Professor Sinead Delany-Moretlwe.
These results have major global implications. They reinforce the critical importance of early, school‑based HPV vaccination and provide compelling evidence for countries, particularly those with high HIV prevalence, to implement and sustain national HPV vaccination programmes. Such programmes have the potential to dramatically reduce cervical cancer risk, improve women’s health outcomes, and ultimately save lives worldwide.
South Africa’s public tender framework has long recognised the importance of ensuring reliable, affordable, and uninterrupted access to essential medicines and vaccines, particularly for national immunisation programmes that protect children and vulnerable populations.
While local pharmaceutical manufacturing remains an important national objective, it is equally critical that public procurement decisions prioritise patient access, programme sustainability, and fiscal responsibility, especially in vaccine supply where scale, complexity, and affordability are decisive factors.
Vaccines require scale, specialisation and reliability
Vaccine manufacturing at national immunisation scale requires highly specialised infrastructure, advanced technical capability, strict regulatory compliance, and sustained capital investment. These requirements differ materially from those of many small‑molecule medicines.
“When it comes to vaccines, the overriding priority of the public tender system must be patient access. Scale, affordability, and uninterrupted supply are essential if South Africa is to expand and sustain its national immunisation programmes,” said Simo Masondo, Chairman of the Generic and Biosimilar Medicines Association of South Africa (GBMSA).
Although South Africa has made meaningful progress in strengthening elements of local pharmaceutical capability, vaccine manufacturing readiness varies significantly across product categories, and certain capacities continue to evolve. In this context, national immunisation programme must be supported by a calibrated combination of local and global manufacturing supply, particularly where programme expansion, continuity and affordability are at stake.
A tender system that prioritises supply reliability and scale is essential to ensuring that immunisation program can reach more patients, more consistently and without interruption.
Competitive pricing and demonstrable value for money remain central to the sustainability of South Africa’s public healthcare system. The National Department of Health has consistently emphasised procurement principles that include value for money, open and effective competition, accountability, and equity.
In vaccine procurement, competitive tender outcomes directly enable:
Broader immunisation coverage
Greater reach to children and underserved populations
More efficient use of limited public healthcare resources
Affordability is not a secondary consideration; it is a core enabler of access.
BRICS partnerships as strategic enablers of vaccine access
Trusted international partnerships, particularly within the BRICS ecosystem, play a critical role in supporting South Africa’s vaccine supply objectives. Long‑standing collaborations with partners in countries such as India have consistently demonstrated scale, reliability, regulatory compliance, and significant cost efficiencies in national tenders.
Indian vaccine manufacturers have historically delivered substantial savings to the South African government, in some cases exceeding R2 billion on a single vaccine programme, while supporting the expansion and sustainability of national immunisation coverage.
These partnerships should be viewed not as alternatives to local capability, but as essential enablers of immediate access, affordability, and programme continuity, particularly in vaccine categories where local scale is still developing.
A pragmatic and patient‑centric path forward
“A pragmatic, balanced approach allows South Africa to meet today’s immunisation needs while continuing to build capability over time. This is not a choice between localisation and access; it is about sequencing decisions responsibly so that patients always come first,” Masondo said.
Such an approach ensures:
Reliable and uninterrupted vaccine supply
Expanded immunisation reach for South African children
Responsible stewardship of public healthcare funds
Long‑term programme sustainability
Strengthened international cooperation within BRICS and other trusted partnerships
By prioritising access, affordability, and scale in vaccine procurement, South Africa can protect its immunisation programmes today while continuing to build manufacturing capability over time, without compromising patient outcomes or fiscal sustainability.

A cutting-edge, South African-led HIV vaccine trial built on decades of research recently kicked off in Cape Town. Spotlight unpacks what exactly is being studied, and how the resilience, tenacity and urgency of a group of dedicated South African researchers made it possible.
Antiretroviral medicines can suppress HIV in the body and keep people healthy, but we do not yet have a viable cure for HIV or an effective vaccine. It is not for lack of trying. For decades now, researchers across the globe have been working hard to develop a vaccine against HIV. While there have been several major disappointments along the way with vaccines failing in large studies, a new clinical trial in South Africa might soon find vital answers that could reinvigorate the field.
The study was originally set to start in 2025, but researchers had to pivot and find new funders when the United States abruptly terminated much of its international research funding. After some scrambling, a stripped-down version of the study has now started. Rather than being cowed by having to delay, and reduce the size of the study, it seems that forging ahead without US support have sparked a pervasive sense of optimism.
“It feels like the most coherent, involved clinical trial I’ve ever been involved in – so that’s why I’m so excited. I feel like it’s going to lead to big things because it’s bringing so many people with it,” says Professor Penny Moore, a leading virologist who is heading up the laboratory work for the study.
That optimism is tangible at the clinical trial site in the Old Main Building at Groote Schuur Hospital in Cape Town. During our visit, one can’t help noticing how the Desmond Tutu Health Foundation’s signature rainbow logo and colourful walls and furniture breaks through the dark hospital corridors and ancient elevators.

Like the sugar coating on a Smartie
In the clinical trial, called BRILLIANT 011, researchers are testing two immunogens, says Dr Sheetal Kassim. She is the site lead for the Desmond Tutu Health Foundation’s clinical trial site at Groote Schuur Hospital and Principal Investigator for the trial. An immunogen is an engineered agent designed in a laboratory, she explains, to cause a specific immune response. The aim of this trial, Kassim says, is to see if these two immunogens are able to trigger the development of cells that have the potential to later become special immune cells called broadly neutralising antibodies.
Once HIV is in someone’s body, it is able to stick around mainly by taking over immune cells called CD4 cells. It evades the immune system by constantly mutating so the antibodies sent to find it don’t recognise it. Eventually the infected CD4 cells burst and die, but HIV keeps replicating, weakening the immune system.
Broadly neutralising antibodies are special antibodies that can recognise and fight a range of different HIV strains, no matter how much it has mutated, says Moore.
HIV is covered in something called glycans that make it hard for antibodies to reach it, she explains. Think of these glycans as the hard sugar coating around a Smartie. A broadly neutralising antibody can recognise the parts of the virus that won’t change when it mutates. This allows the broadly neutralising antibody to be able to reach through that hard outer coating, bind to the virus and destroy it.
Two immunogens, given at the same time
In late January, the researchers enrolled the first of an expected 20 healthy participants, who do not have HIV, and are at a low risk for getting HIV. By mid-February, seven participants had received their first shots.
It is a phase one study, which is to say it is still very early days. A phase one trial looks at the safety of a drug or vaccine in a small number of individuals, while a phase two trial looks at safety in slightly larger groups and gives some early indication of efficacy. A phase three trial is much larger and looks mainly at efficacy.
The researchers are testing the immunogenicity – essentially the ability to elicit an immune response against HIV – and safety of the two immunogens in humans for the first time. A special adjuvant – known as SMNP – is being added to the agents to enhance their effect.
The hope is that the study results will help identify a potential vaccine candidate to test in future, larger studies, says Kassim. “We’re not going to come out of this study and say we have a vaccine that can prevent or cure HIV,” she says. “But we will have information on these immunogens that will help us in the future.”
It has already been shown that the two immunogens can target the type of antibody cells that have the potential to become broadly neutralising antibodies and essentially switch them on. Think of it as a talent finding agency, says Kassim, that can find the next “star” that can become an important broadly neutralising antibody.
The two shots are injected into the muscle of the arm on three separate visits, she says. The first is given after a rigorous health screening. The second is given one month later and the final dose is given three months later. Doing it this way, primes the immune system with the first shots and then the doses that follow boost the initial effects.
Putting ‘the puzzle pieces together’
Research studies like this one is still in the “experimental medicine” phase, Professor Linda-Gail Bekker, CEO of the Desmond Tutu Health Foundation, tells Spotlight. She says results from this study will help “put the puzzle pieces together” to get a clearer picture of which immunogens should eventually be tested in a phase three efficacy trial.
The trial is novel because of the use of two immunogens instead of one. Professor Glenda Gray, Chief Scientific Officer at the South African Medical Research Council (SAMRC), refers to it as an “ambitious and aggressive approach”. She tells Spotlight that usually researchers follow a sequential pattern, testing one immunogen, then another and eventually testing them together. The problem with this is that if they don’t work together, you’ve lost up to five years of research.
“We also have this philosophy of ‘failing fast’,” Gray says. “[I]nstead of wasting money and time and effort, we need to know whether our strategy is going to work or not in the beginning.”
A proudly South Africa trial
Beyond the cutting-edge science, it’s clear that what makes this trial so unique is the people involved.
Bekker describes the trial as “proudly South African”. She says: “It’s just terrific that we’re doing this end-to-end. We’re involving the community, the recruiters are people from the country, the people who are taking the blood are people from the country, the people who are doing the laboratory science are from the country, and we’re doing it for people in our country.”
Moore adds: “We’ve got so many people in the background working on these trials at the clinical sites and here in my lab…There’s this huge mass of people all working together on this trial.”
BRILLIANT 011 is one of 22 trials currently running at the Groote Schuur Hospital site, Henriette Kyepa the Unit Manager for the site, tells Spotlight. The doors open at 07:00 and the last participant leaves by 15:00, and since at least 40 participants are being seen each day, she describes the goings on as “bustling”.
The hospital has an illustrious medical history, with the first human heart transplant having been performed in the Old Main building – the Christiaan Barnard Heart Museum is just a few floors down. The Desmond Tutu Foundation’s research site has been operating at the hospital for more than 10 years.
During a tour of the unit, Spotlight was led through a waiting area, pharmacy, and two nursing areas – where patient’s vitals are checked and data captured. Staff manning the different stations were busy, but friendly and took requests for photographs in their stride. There are four doctors’ rooms and a procedure room, equipped with things like a crash cart in case anyone has a bad reaction to a drug or device that’s being tested. The site also includes private counselling rooms and a purple, gender inclusive bathroom. Down the hall, there is a hospital ward and a small laboratory, which is shared with the University of Cape Town Clinical Research Unit, for patients that need timed blood draws for studies where drug levels are being monitored.
But before they come to the site, the first point of contact for many potential trial participants – for BRILLIANT 011 and other studies – are the community recruiters. This is a team of three outreach workers led by Amelia Mfiki, who is the community liaison officer for the Desmond Tutu Health Foundation and lead recruiter. Their job is to keep the local communities updated on what the site is doing, get their feedback and to find participants who fit the eligibility criteria for different studies.
If someone is interested in a study, Mfiki explains, they are sent to the site for an information session, where the trial, eligibility criteria and the commitment required to participate is clearly unpacked. If they meet the criteria and want to participate, they go through a further informed consent process and screening. With a big smile, she tells Spotlight there has been a lot of requests for information about the BRILLIANT 011 trial.
Once enrolled, clinical trial participants will spend a lot of time with the nursing staff. Among them is Viwe Soko, a senior nurse who says “making people smile” is part of his job.
How they’ll test if it works
The BRILLIANT 011 trial participants will need to come back roughly two weeks after each jab to have white blood cells – which contain the cells that can become broadly neutralising antibodies – extracted from their blood through a process called leukapheresis. This is how the researchers are looking for those “star” antibodies that have the potential to become broadly neutralising antibodies.
Basically, the leukapheresis machine draws a participant’s blood and runs it through a centrifuge that separates the white blood cells from all the other cells in the blood, explains Moore. The white blood cells are collected into a sterile blood bag, while the rest of the blood goes back into the participant. (Here’s a useful video showing how it works).
Hundreds of millions of white blood cells are collected each time a participant goes through this process, according to Moore. “The reason we need a crazy number [of cells] is because the responses that we’re looking for are rare as hen’s teeth,” she says.
The cells are then processed in the laboratory at Groote Schuur Hospital and sorted into different tubes containing 20, 50 and 100 million cells respectively, frozen, and then sent more than 1 000 km away to Moore’s laboratory at Wits University in Johannesburg.
Once there, the thawed antibodies are run through a special machine called a flow cytometer, which is able to spit out individual cells of interest via an ultra-thin stream. The cells are mixed with a dye to make them easy to spot, says Moore. Then a laser and computer, under the supervision of a highly trained scientist sorts the cells to isolate the types of antibodies they’re interested in.
These precursors of the broadly neutralising antibodies are “structurally weird”, said Moore, some of them have really long “arms” that can reach through HIV’s hard outer coating, or really short “arms” to get close to it.
At the end of the process, there might be 100 relevant cells which then go through a process called next generation sequencing. The researchers are looking for two specific genetic signatures that will show that the right antibody was produced. Moore likens this to a cell that has “a purple head and an orange arm” and is extremely rare. Once they find all the cells with these signatures, they count them.
At its core, Moore says, they’ll know the immunogens have worked if they find more “cells with purple heads and orange arms” than has been seen in other vaccine trials that only used one immunogen.
“I think this is some of the most important work I’ll ever do,” Moore says. “It feels like 20 years of basic science has finally paid off.”
She has been monitoring the antibody responses for the CAPRISA 002 cohort for the last two decades. It is within this cohort, that a handful of women living with HIV who had naturally produced broadly neutralising antibodies were discovered and since studied. This is part of the foundation on which the BRILLIANT 011 trial has been built.
Because of all the lab work and specialised equipment required, this kind of study is expensive to run. For the study period, it costs about R1 million for each participant to be in the trial, according to Gray. This trial has a budget of R25 million, the bulk of which has been supplied by the Gates Foundation. Some emergency funding from the SAMRC was used to make up the rest.
‘Nobody gets the urgency’ like South Africa
This amount is a far cry from the five-year USAID grant worth over $45 million, that was originally awarded to the BRILLIANT Consortium in 2023. This ambitious African-led Consortium, led by Gray and run out of the SAMRC, had big plans for HIV vaccine research and capacity development across Sub-Saharan Africa. As Spotlight previously reported, the Consortium planned to conduct three HIV vaccine trials, about one a year, and develop laboratory capacity for this kind of research across the African continent.
In the end, they only had the USAID grant for a year, just enough time to set everything up for BRILLIANT 001, a much flashier version of the trial that is currently running. It was set to take place at sites in Uganda, Kenya, Zimbabwe, South Africa and Nigeria, and recruit 60 participants, according to Gray.
“We were actually due to start it [BRILLIANT 001] in February of 2025. And then it was stopped,” Bekker says. “And so, we went through the five stages of grief and finally got to the point of acceptance. And with acceptance came a real sort of verve to try and find alternative funding.”
Essentially, the researchers were racing against the clock on multiple fronts.
The immunogens, which had been donated by labs in the Netherlands and the United States were already in the country and had expiration dates that meant the study could not be delayed indefinitely (in the end the study would start in time for this to no longer to be a concern).
But more importantly there was the roughly eight million people living with HIV in the country.
“I think nobody gets the urgency like a South African,” Bekker says. “It’s very real in our lives that this virus continues to devastate [and] change the lives of people we love and serve and work with. So that sense of urgency is very real within us.”
The team wrote up a new funding proposal and study protocol, which Bekker describes as a much lighter version, “pared down to the absolute bones”. They presented this to the Gates Foundation, which agreed to provide funding for this leaner version, and the team pushed to get everything else in place.
Gray weighs in on how, just as the process was taking off again and the protocol had been submitted to the South African Health Products Regulatory Authority (SAHPRA), which has to review and approve all clinical trials conducted in the country, the adjuvant they had planned to use was recalled by the manufacturer. Luckily, they had had some warning this might happen and had a protocol using another adjuvant ready to go. And just a year after the original trial was meant to start, they were able to kick off BRILLIANT 011.
“No one works in these timelines,” says Gray, adding that part of the reason they were able to pull this off was because of how well the team works together. “Everyone puts in more than their pound of flesh, they work incredibly hard…everyone believes in the kind of programme that we’re trying to put together,” she adds.
‘I want to help my community’
Participants for the 011 trial are reimbursed for their time and travel using a SAHPRA approved model. However, Kassim says there appears to be a more altruistic motive among participants, with some sharing sentiments like: “I want to help people. I want to help my community.”
Bekker notes a similar theme that’s held true over the last two decades of HIV vaccine research. “It’s incredibly encouraging, but it’s also incredibly humbling that, in a country like ours, where people have so many other challenges, that they could … [have] an entirely altruistic motivation, that they are digging deep within themselves and saying: ‘I’m motivated because I want to see an end to the suffering’.”
“If we truly want to bring this epidemic to an end and eliminate transmission, we will need a vaccine,” says Bekker. “And imagine, a world where you could get your vaccination, at age 10 or even younger, and then not have to think about HIV ever again.”

Sanofi is pleased to share that the South African Health Products Regulatory Authority (SAHPRA) has granted registration for Beyfortus® (nirsevimab), a long-acting monoclonal antibody designed to protect infants against Respiratory Syncytial Virus (RSV).
Beyfortus® is the first long-acting monoclonal antibody designed to provide protection across the RSV season for all infants, including those born at term, preterm, or with underlying conditions. It is given as a single intramuscular dose just before or during the RSV season¹ and is expected to be available before the 2026 RSV season.
RSV is one of the leading causes of Lower Respiratory Tract Infections (LRTIs) such as bronchiolitis and pneumonia in young children, and a major driver of hospitalisation in infants under one year of age.3 Globally, RSV is responsible for 20 to 40% of pneumonia and 40 to 80% of bronchiolitis hospitalised cases among infants under one year of age.2
It was estimated that in a year, RSV caused around 33 million acute lower respiratory infections in children younger than five years, resulting in 3,6 million hospitalisations and over 100 000 RSV-attributable deaths globally3. RSV-related medical costs in this age group are estimated at €4.82 billion per year, including hospital, outpatient, and follow-up care7.
In South Africa, RSV infections occur year-round with a strong seasonality from February to May4. Each year in South Africa, there are approximately 96 000 cases of RSV severe acute respiratory illnesses in children under five years of age, and among newborns under one month, about one in seven requires admission for severe RSV9. The incidence and severity of RSV LRTI are highest in infants under 6 months of age, representing 22% of all-cause hospital admissions in this age group. 41% of the LRTI-related hospitalisations are attributable to RSV.5
RSV infections also have long lasting consequences as a first episode of RSV LRTI is associated with an increased risk of subsequent LRTIs. In addition, RSV is associated with recurrent wheezing in early childhood.6
Though risk factors such as prematurity and underlying conditions will increase the probability and severity of RSV infections in children, the majority of severe RSV outcomes occur in healthy full‑term infants. They represent the majority of ICU admissions (65.8%) and mechanical ventilation cases (59.8%) among RSV‑infected infants, and globally, healthy infants account for around 57% of RSV‑related deaths.10-11 For this reason, all infants are at risk of RSV disease.
A single dose of Beyfortus® provides immediate and season-long protection, lasting for at least five months, corresponding to a typical RSV season¹. In the MELODY phase III trial*, nirsevimab reduced medically attended RSV-LRTI by 74.5% and hospitalisations by 62.1% compared with placebo,8 while the HARMONIE real-world study found an 82.7% reduction in RSV-related hospitalisations through 180 days after immunisation14. Beyfortus® demonstrated a consistent safety profile across term, preterm, and high-risk infants, with the most common adverse reactions being mild rash (0.7%), fever (0.5%), and injection-site reactions (0.3%)¹.
Beyfortus® has also demonstrated its strong public health impact in real-world settings. Following its introduction in 2024 in Chile and in 2023 in Galicia, Spain, the effectiveness of Beyfortus® against RSV-related LRTI hospitalisations was estimated to be 76.4% and 85.9%, respectively. In Chile, Beyfortus® demonstrated 49.7% effectiveness against all-cause hospitalisation. 12-13
“RSV causes a great burden on families and the healthcare systems in South Africa and worldwide,” says Diane Buron, South Africa Medical Head for Sanofi Vaccines. “It is a leading cause of infant hospitalisation during the season and Beyfortus® has the potential to change that. With only one dose, babies will be effectively protected throughout the season and thousands of cases and hospitalisations can be averted.”
“Because the majority of RSV cases are in term and healthy infants,” says Buron “proposing this innovative and effective protection to all infants will have a significant impact on the families and healthcare system.”
More than 6 million infants worldwide have now received Beyfortus®, supported by over 40 real-world studies across four continents, in both the Northern and Southern hemispheres. The introduction of Beyfortus® in South Africa is a significant advancement in paediatric respiratory protection and supports the global goal of reducing preventable infant morbidity and mortality linked to RSV8.
*The Phase 3 MELODY trial was a randomised, double-blind, placebo-controlled trial conducted across 21 countries designed to determine the safety and efficacy of Beyfortus® against medically attended LRTD caused by RSV in healthy term and late preterm infants (35 weeks gestational age or greater) entering their first RSV season, including efficacy against severe disease such as hospitalisation, through 150 days after dosing. The primary endpoint was met, reducing the incidence of medically attended RSV LRTD by 74.5% (95% CI 49.6, 87.1; P<0.001) compared to placebo. The efficacy of Beyfortus® against the secondary endpoint of hospitalization was 62.1% (-8.6, 86.8). A pre-specified pooled analysis of the Phase 3 MELODY trial showed the efficacy of Beyfortus® against medically attended RSV LRTD and medically attended RSV LRTD with hospitalisation was 79.5% (95% CI 65.9, 87.7; P<0.0001) and 77.3% (95% CI 50.3, 89.7; P<0.001), respectively.

New research reveals that activating the brain’s reward system through positive anticipation strengthens the immune response and increases antibody production
Can positive anticipation that activates the brain’s reward system strengthen the body’s immune defences? A new study by Tel Aviv University, the Technion, and Tel Aviv Medical Center (Ichilov), published in the prestigious journal Nature Medicine, provides the first evidence in humans that brain activity associated with the expectation of reward has a measurable effect on the body’s response to a specific vaccine.
Eighty-five healthy volunteers participated in the experiment. Some underwent special brain training using fMRI neurofeedback technology – a method that enables individuals to learn, in real time, to regulate activity in specific brain regions through reinforcing learning. The aim of the brain training was to increase activity in a key region of the brain’s reward system including the Ventral Tegmental Area (VTA), which is responsible for dopamine release in the context of mental activity related to the expectation of positive outcomes and motivation to obtain rewards. Participants were instructed to modulate their brain activity using various mental strategies (eg, thoughts, feelings, memories) while monitoring positive feedback about the strategy that was successful in regulating their brain.
From Brain Activation to Antibodies
Immediately after completing the brain training, all participants received a hepatitis B vaccine. The researchers then tracked the immune response through a series of blood tests, measuring levels of specific antibodies produced following the vaccination.
The results showed that participants who succeeded in significantly increasing activity in the brain’s reward region also demonstrated a greater increase in antibody levels after vaccination. The association was specific to the VTA and was not observed in other brain regions used for control purposes (such as the hippocampus), nor in other reward-system areas linked to different reward-related experiences such as pleasure and satisfaction. In other words, the effect was both anatomically and mentally specific.
The Role of Positive Anticipation
Furthermore, an in-depth analysis of the mental strategies participants used during training of the VTA (and not other regions) revealed that those who focused on positive anticipation, such as belief in a good outcome, or the expectation of something positive about to happen, were able to maintain higher VTA brain activity over time, which was also associated with a better immune response. In other words, the researchers identified a link between reward-system brain activity, a mental state of positive anticipation, and the body’s response to an immune challenge.
According to the research team, this is not “positive thinking” in the popular sense or a New Age slogan, but a measurable neurobiological mechanism – related, among other things, to the well-known placebo effect in medicine (a therapeutic response beyond a specific medical intervention). “We show that mental states have a clear brain signature, and that this signature can influence physiological systems such as the immune system,” explain the researchers.
While the study does not propose a substitute for vaccines or medical treatment, it opens the door to new, noninvasive approaches that may one day strengthen immune responses, improve the effectiveness of medical treatments, and even contribute to fields such as immunotherapy and the treatment of chronic immune pathologies. The researchers note that the study’s findings underscore a broader message: the mind–body connection is not merely a theoretical concept, but a real biological process that can be measured, trained, and potentially harnessed to promote better health.
Implications for Medicine and Health
The research team adds that the findings highlight the potential inherent in integrating neuroscience, psychology, and medicine. “Our study shows that the brain is not only a system that responds to the body’s state of health, but also an active player that influences it,” say the researchers. “The ability to consciously activate brain mechanisms associated with positive anticipation opens a new avenue for research and future treatments – as a complement to existing medicine, not as a replacement. In the future, it may be possible to develop simple, noninvasive tools to help strengthen immune responses and enhance the effectiveness of medical treatments by relying on the brain’s natural capacity to influence the body. However, it is important to emphasise that activation of the reward system and its effect on immune response vary between individuals. Therefore, this approach cannot replace existing medical treatments, but may well serve as an additional supportive component.”
