President Biden Orders Deeper Probe into COVID Origins

On By ModernMedia

US President Joe Biden has ordered intelligence officials to “redouble” their efforts in investigating the origins of COVID, as well as the theory that it was a ‘lab leak’ in China.

This comes days after details of a US intelligence report emerged in the Wall Street Journal, claiming that three doctors working at the Wuhan Institute of Virology had fallen ill with COVID-like symptoms in November 2019 – about when epidemiologists believe SARS-CoV-2 first began circulating in humans. 

Mr Biden said the US intelligence community was divided on whether it was the result of a lab accident, or from jumping from human to animal. Mr Biden asked the groups to report back to him within 90 days.

China’s embassy in the US made a warning statement posted on its website, without mentioning the president’s remarks. “Smear campaigns and blame shifting are making a comeback, and the conspiracy theory of ‘lab leak’ is resurfacing.
“To politicise origin tracing, a matter of science, will not only make it hard to find the origin of the virus, but give free rein to the ‘political virus’ and seriously hamper international cooperation on the pandemic,” it said.

Authorities linked early COVID cases to a seafood market in Wuhan, leading scientists to theorise the virus first passed to humans from animals.

Why now?

In a White House statement released on Wednesday, President Biden said he had asked for a report on the origins of COVID after taking office, “including whether it emerged from human contact with an infected animal or from a laboratory accident”. He asked for “additional follow-up” on receiving the report.

Mr Biden said most of the intelligence community had “coalesced” around those two scenarios, but “do not believe there is sufficient information to assess one to be more likely than the other”.

The president has now asked agencies to “redouble their efforts to collect and analyse information that could bring us closer to a definitive conclusion”, and report to him within 90 days.

He concluded by saying the US would “keep working with like-minded partners around the world to press China to participate in a full, transparent, evidence-based international investigation and to provide access to all relevant data and evidence”.

Beijing meanwhile has previously suggested a possible US lab origin for COVID. The Chinese embassy said it supported a full investigation into “some secretive bases and biological laboratories all over the world”.

Mr Biden’s statement coincided with a CNN report that the president’s administration earlier this year shut down a state department investigation into a possible lab leak origin.

The ‘lab leak’ theory

When they first arose last year, the laboratory leak allegations were widely dismissed as a fringe conspiracy theory, with many US media outlets describing the claims as debunked or false after then-President Donald Trump said COVID had originated from the Wuhan Institute of Virology.

Two months ago, the World Health Organization (WHO) issued a joint report with Chinese scientists on COVIDs origins, rating the likelihood of an accidental lab release as “extremely unlikely”. However the WHO Director-General Tedros Adhanom Ghebreyesus said that he was not satisfied that the investigation had looked at this possibility enough to rate. The investigation only stirred up more interest in the ‘lab leak’ theory, with 18 scientists signing an open letter calling for more investigation before it could be ruled out.

There is little evidence for the ‘lab leak’ theory in the public domain however, and intelligence reports such as the one the Wall Street Journal based its story on are often of unproven provenance. 

Chief White House medical adviser Anthony Fauci still believes that COVID jumped from animals to humans, though this month he admitted he was no longer confident COVID had developed naturally.
Mounting pressure

Mr Biden’s statement comes the day after Xavier Becerra, US secretary for health and human services, urged the WHO to ensure a “transparent” investigation into the virus’s origins.

“Phase 2 of the Covid origins study must be launched with terms of reference that are transparent, science-based and give international experts the independence to fully assess the source of the virus and the early days of the outbreak,” Mr Becerra said.

On Tuesday, Mr Trump sought to take credit in an emailed statement to the New York Post, saying: “To me it was obvious from the beginning but I was badly criticised, as usual. Now they are all saying: ‘He was right.'”

COVID Sniffer Dogs Have a 94% Sensitivity, Study Shows

On By ModernMedia

Quickly and efficiently screening incoming travellers for COVID is currently beyond present technology, but dogs — with their keen sense of smell that has aided humans for thousands of years — may be a solution.

An Ekurhuleni-based company is in the final stages of training dogs to be deployed as COVID sniffers at South African points of entry, just in time for the expected third wave, eNCA reports.

Currently, the most widespread test is the rapid antigen (lateral flow) test, which has been shown to produce more false positives for COVID than real detections in low prevalence situations — such as travellers arriving in a country.

Alternatively, the polymerase chain reaction (PCR) test has the greatest sensitivity but is time-consuming and expensive. And most currently available tests involve nasopharyngeal swabs — an unpleasant experience for most people. 

Dogs, with their keen sense of smell have long been used to sniff out drugs and explosives. In recent years they have also been trained to sniff out certain cancers and malaria, although they are not regularly used for this.
Using medical sniffer dogs has the advantage of being extremely quick and could be used in resource-constrained settings.

In the first months of the pandemic, many wondered whether dogs could in fact smell the disease, and began training dogs to see if it was possible. 
Past studies had already established that the volatile organic compounds (VOCs) released in body odour change during respiratory infections. VOCs associated with COVID infection showed a clear distinction between infected and uninfected individuals, suggestive of a strong, distinctive smell.

Initial trials with trained sniffer dogs at airports in France, Lebanon and FInland found that the dogs were even capable of detecting infection before it could be picked up with clinical tests.

A recent study led by the London School of Hygiene & Tropical Medicine (LSHTM) estimated that a plane with 300 passengers could be screened in 30 minutes with two sniffer dogs, and only those passengers identified by the dogs would be required to take a PCR test.

The study, which is not yet peer-reviewed and which is currently available as a pre-print, found that dogs could be trained to detect COVID in 94.3% (test sensitivity) — comparable to the gold standard of PCR tests with 97.2% sensitivity. They also have a specificity of 92%, meaning that they have a low rate of false positives.

Dr Claire Guest, Chief Scientific Officer at Medical Detection Dogs, which assisted in the study, said: “These fantastic results are further evidence that dogs are one of the most reliable biosensors for detecting the odour of human disease. Our robust study shows the huge potential for dogs to help in the fight against COVID.

“Knowing that we can harness the amazing power of a dog’s nose to detect COVID quickly and non-invasively gives us hope for a return to a more normal way of life through safer travel and access to public places, so that we can again socialise with family and friends.”

Besides simple detection, the dogs could also serve as a visible deterrent to people wanting to travel with fake COVID passports, the authors said.
The findings of their study also provided valuable knowledge which could be applied to future pandemics.
The authors acknowledged the limitation that the dogs were conducting the tests in a controlled environment as opposed to the real world.

Vaccine Flops and Shortages Leave SA with no Covax Shots

On By ModernMedia
Image by Quicknews

Nearly six months after South Africa’s first procurement deal was made with the Covid-19 Vaccines Global Access (Covax) programme, but vaccine flops and shortages in supply have left South Africa empty-handed, while Covax struggles to even meet its June delivery goal.

South Africa’s vaccine rollout has been anything but smooth. The first batch of vaccines, produced by the Serum Institute of India (SII), arrived in the country on 1 February but were abandoned a week later after a study found it was ineffective against the 501Y.V2 variant. That first batch of one million doses were sold onto the African Union (AU) and the remainder of the order refunded.

The health department switched to the Johnson & Johnson (J&J) single-dose shot and vaccinated nearly half a million healthcare workers until its use was also halted over blood clot concerns. Phase 2 of the rollout is using the Pfizer vaccine. Fortunately, it has been found that it can be stored at much higher temperatures than its previous ultracold requirements, making it easier to distribute.

However, the failure to join Covax by December 2020 was an early warning sign over the government’s handling of vaccine acquisition. The Covax iniative, led by the Vaccine Alliance (Gavi) and World Health Organization (WHO) to supply vaccines to poorer nations, were expected to kickstart South Africa’s rollout.

Missing that first deadline, the health department and Solidarity Fund confirmed, on 22 December 2020, that a down payment of R283 million had been made to secure doses through Covax.

Vaccine flip-flopping
At first, South Africa was to receive almost 2.5 million doses of AstraZeneca vaccine, but the country’s decision to abandon the use of AstraZeneca caused severe delays. The country’s allocated AstraZeneca doses were taken back into the Covax programme.

“South Africa was allocated 2 426 400 doses of the AstraZeneca vaccine… it has requested to be allocated another vaccine in place of AZ, and will receive allocations of alternative vaccines instead,” Gavi spokesperson Evan O’Connell told Business Insider South Africa.

“It has already been allocated, at this stage, 1,392,300 doses of the Pfizer vaccine, allocated for Q2 2021.”

According to Covax’s first-round schedule,  South Africa was due to receive 117 000 Pfizer doses before April. But Covax’s deliveries are falling behind, putting initiative’s ability to meet its second quarter target.

On 17 May UNICEF Executive Director, Henrietta Fore announced that the Covax facility would shortly have delivered 65 million doses, which should have been 170 million doses by that time.

“By the time G7 leaders gather in the UK next month, and as a deadly second wave of COVID will likely continue to sweep across India and many of its South Asian neighbours, the shortfall will near 190 million doses.”

Covax hamstrung by Indian COVID crisis

India’s COVID crisis has hamstrung Covax’s aim of delivering 237 million doses of AstraZeneca vaccine in the first half of 2021. With India having the world’s highest infection numbers and deaths since April, the SII, which produces AstraZeneca doses for Covax, announced that it would halt foreign supply until December at the earliest.

“We continue to scale up manufacturing and prioritise India,” said SII CEO Adar Poonawalla on 18 May. “We also hope to start delivering to Covax and other countries by the end of the year.”

At only 35% of its targeted vaccine deliveries, Covax is calling for renewed funding and donations from developed nations — who are also accused of hoarding vaccines. WHO director-general Tedros Adhanom Ghebreyesus, criticised wealthy nations for continuing a “scandalous inequity” on Monday.

“We need countries to donate tens of millions of doses of vaccines immediately through Covax, which is the agreed global mechanism for distributing vaccines,” stated Ghebreyesus.

“We need companies to help make donations happen fast, and to give Covax the first right of refusal on all uncommitted doses now, in 2021.”

It’s unclear whether the SII’s decision to halt its supply will result in reallocations of the Pfizer doses, on which SA is depending, and which therefore could result in further delays for its Covax-allocated doses.

Little Traitors: Infection-Enhancing Antibodies in Severe COVID

On By ModernMedia

Osaka University researchers have discovered that infection with SARS-CoV-2 results in not only the production of neutralising antibodies that prevent infection, but also of infection-enhancing antibodies.

Both neutralising antibodies that protect against infection as well as infection-enhancing antibodies that increase infectivity are produced after infection with SARS-CoV-2 by analysing antibodies from COVID patients.

Virus-specific antibodies generally are considered antiviral, playing an important role in the control of virus infections. In some cases however, the presence of specific antibodies can benefit the virus. This activity is known as antibody-dependent enhancement of virus infection, a phenomenon in which virus-specific antibodies enhance the entry of virus, and in some cases the replication of virus, into monocytes/macrophages and granulocytic cells through interaction with Fc and/or complement receptors. 

In COVID infections, antibodies that target the receptor binding site (RBD) of the SARS-CoV-2 spike protein play an important function as neutralising antibodies that suppress SARS-CoV-2 infection by preventing it from binding to the human receptor, ACE2. However, the function of antibodies against other sites of the spike protein was not known.

“We found that when infection-enhancing antibodies bind to a specific site on the spike protein of SARS-CoV-2, the antibodies directly cause a conformational change in the spike protein, resulting in the increased infectivity of SARS-CoV-2. Neutralising antibodies recognise the RBD, whereas infection-enhancing antibodies recognise specific sites of the N-terminal domain (NTD),” explained lead researcher Professor Hisashi Arase. “Furthermore, the production of infection-enhancing antibodies attenuated the ability of neutralising antibodies to prevent infection.”

The study found that patients with severe COVID produced more infection-enhancing antibodies. Non-infected individuals were also found to possibly have small amounts of infection-enhancing antibodies.

Though infection-enhancing antibodies may be involved in the development of severe disease, further research is necessary to determine whether they are in fact involved in the worsening of infection in the body.

A possible benefit would be that by analysing the antibody titer of infection-enhancing antibodies, it would be possible to see who would be prone to severe COVID. The findings are also important for the development of vaccines that do not induce the production of infection-enhancing antibodies.

“It is important to analyse not only neutralising antibodies but also infection-enhancing antibodies. In the future, it may be necessary to develop vaccines that do not induce the production of infection-enhancing antibodies, because infection-enhancing antibodies may be more effective against mutant strains in which neutralising antibodies are not sufficiently effective,” says Professor Hisashi Arase.

Risk of COVID Infection Tripled in Healthcare Workers

On By ModernMedia

A study of healthcare workers has shown their likelihood of being infected with COVID during the pandemic was three times higher compared to the general population, with about one in five of those infected workers being asymptomatic and unaware they had COVID.

The study also shows that it was not only frontline staff who faced the higher risk, suggesting that there was transmission between staff and within the wider community. The results are published in ERJ Open Research.

However, health care workers who had been infected were very unlikely to contract COVID a second time in the following six months.

The research was led by Professor James Chalmers, a consultant respiratory physician from the University of Dundee.

“We have always believed that front line health workers face a high risk of contracting COVID and that’s why we’ve tried to ensure they have the PPE needed to protect themselves,” said Prof Chalmers. “But many questions remain about the level of this risk and what other measures we can take to protect staff and reduce transmission of the disease.”

The study recruited 2063 staff working in a wide variety of healthcare roles in the East of Scotland. Between May and September 2020, the participants had blood tests for COVID antibodies, a very accurate indication of prior COVID infection. The researchers also recorded whether any participants developed an infection in subsequent months.

The health care workers results were compared with a randomly selected control group of blood samples taken by local GPs during the same time period.

These blood tests showed that 300 (14.5%) of the healthcare workers had been infected, a rate more than triple the proportion of people infected in the local population. The highest rates of infections among the workers were found in dentistry (26%), health care assistants (23.3%) and hospital porters (22.2%). The rate among admin staff was the same as that of doctors (21.1%).

Rates among people working in areas of the hospital where COVID patients were being treated were somewhat higher than those working in non-COVID areas (17.4% vs 13.5%). However, the majority of infections were in staff who were not working directly with COVID patients, suggesting there was transmission between staff or infections acquired in the community.

Out of the 300 healthcare workers testing positive, 56 (18.7%) did not think that they had ever caught COVID and were totally asymptomatic. This is an important finding, according to the researchers, since people without symptoms are likely to go to work, potentially infecting others.

In the months following their blood tests, 39 workers developed a symptomatic COVID infection, but only one of these was a worker who had previously tested positive. This equates to an 85% risk reduction, similar to the level of protection provided by COVID vaccines.

Prof Chalmers said: “A lot of attention during the pandemic has been around PPE for doctors and nurses but we found that dentists, healthcare assistants and porters were the staff most likely to test positive.

“We continued to monitor staff for up to seven months and found that having a positive antibody test gave 85% protection against a future infection. This is really good news for people who have already had COVID-19, as it means the chances of a second infection are very low.”

The team hopes to continue the research to see how long immunity persists and how vaccination affects infections among healthcare workers.

Professor Anita Simonds, President of the European Respiratory Society and Consultant in Respiratory and Sleep Medicine at Royal Brompton Hospital, UK, was not involved in the research, offered comments.

She said: “This research shows the high levels of COVID infection among all healthcare workers, with the highest evidence of infection in dentists, healthcare assistants and porters. Staff working in critical care, who are likely to have been protected by using personal protective equipment at all times, were not disproportionately affected.

“It should be noted that among administrative staff, 21.1% were found to have been infected with COVID, indicating that all those working directly with patients, and those working in other hospital roles are at risk, and vaccination and risk assessment for appropriate levels of PPE in all these frontline groups are crucial.”

Case Positivity Rate in SA Breaches The Crucial 10% Mark

On By ModernMedia

Although new COVID cases have not yet shown an upward surge, the fact that the test positivity rate had climbed past 10% is cause for concern.

According to health minister Dr Zweli Mkhize, the 2383 new infections recorded in the past 24 hours came from 23 352 tests at a positivity rate of 10.2%. Yesterday the positivity rate stood at 9.86%, and in the days beforehand had been gradually creeping upward.

The government has previously expressed concern when the positivity rate (the percentage of COVID tests that return positive) reaches the 10% and 12% marks. In late November, ahead of the second wave, the case positivity rate was 14.5%. Some provinces of South Africa are reporting rates well in excess of this, particularly the Northern Cape which last week had a reported positivity rate of 24.1%.

Dr Mkhize also reported that there were 72 Covid-19 related deaths in the past 24 hours. The health minister also reported that across SA there were now 171 860 people who had received their first shot of the two-dose Pfizer vaccine.

With these latest figures, there are now 1 637 848 cumulative cases and 55 874 cumulative fatalities since the outbreak of the coronavirus in SA in March last year. However, the true toll may be much higher, as South Africa’s ‘excess deaths’, those which are above the average rate of deaths from all causes, were up to 2.67 times higher than the official toll. A report from a team at the SA Medical Research Council and University of Cape Town believed that around 85% of those excess deaths were due to COVID.

Indian Doctors Hit Back at Guru’s Inflammatory Remarks

On By ModernMedia

Doctors in India have hit out against yoga guru Baba Ramdev over his controversial statements against modern medicine and mocking of COVID patients.

Recently, the controversial guru said that tens of thousands died of COVID after taking modern medicines, and also mocked patients for trying to get oxygen cylinders. 

The guru subsequently withdrew his statement after being criticised by the country’s health minister. But on Monday he again took a swipe at modern medicine for not having a cure for some diseases.

Despite India’s modern allopathic healthcare system, alternative therapies like ayurveda and homoeopathy are hugely popular in India. This has helped many gurus to launch successful businesses with sales of herbal medicines and products. India also has a Ministry of Ayurveda, Yoga & Naturopathy, Unani, Siddha and Homoeopathy (Ayush) that promotes traditional medicine systems.

The Indian Medical Association (IMA), which represents allopathy doctors in India, has criticised the guru for his “insensitive” remarks in the middle of the pandemic. Such statements from a guru with millions of followers were “irresponsible and demoralising”, said doctors spoken to by the BBC.
The country has been grappling with a surge of infections caused by a ‘double mutant’ SARS-CoV-2 variant as well as prematurely relaxed social distancing rules.

The controversy
A video of Baba Ramdev mocking patients for trying to find oxygen went viral earlier this month, making references to oxygen shortages in several cities in April and May.

“God has given us free oxygen, why don’t we breathe that? How can there be a shortage when God has filled the atmosphere with oxygen? Fools are looking for oxygen cylinders. Just breathe the free oxygen. Why are you complaining about shortage of oxygen and beds and crematoriums?” he said.

The statement drew sharp criticism from doctors and families of COVID patients who demanded an apology.

Just two weeks later, another video surfaced in which he criticises doctors, blaming COVID deaths on them. Many doctors expressed their anger over Twitter, some went so far as to demand his arrest. In the face of mounting pressures, India’s Health Minister Dr Harsh Vardhan issued a statement asking the guru to withdraw his remarks.

“Allopathy and the doctors attached to it have given new lives to millions of people. It’s very unfortunate for you to say that people died from consuming allopathic medicines.

“We should not forget that this battle can only be won through united efforts. In this war, our doctors, nurses and other health workers are risking their lives to save people’s lives. Their dedication towards serving mankind in this crisis is unparalleled and exemplary,” Dr Vardhan said.

Baba Ramdev withdrew his controversial statement in a Sunday tweet — only to issue a letter the next day asking the IMA why modern medicine had no cure for 25 diseases, including diabetes and hypertension.

This has again infuriated doctors. Prominent pulmonologist Dr A Fathahudeen, who has treated thousands of COVID patients, told the BBC that such statements cause lasting damage.

“For more than a year, healthcare workers like me have been in a war-like situation. We have saved tens of thousand of lives. It’s really unfortunate, insulting and hurtful to read such statements,” he said.

Dr Fathahudeen added that modern medicine had evolved over the years with constant research and studies. “We follow evidence-based practice. At any given time, thousands of researchers are working to come up with cures. Look at the progress we have made in cancer treatment. We have to constantly evolve and learn. It’s hard to trust any branch of medicine that offers absolute cure for every disease.”

Dr Fathahudeen also said that such statements manifest doubts in the minds of people when trust in medicines and vaccines is most needed in the middle of a raging pandemic.

Baba Ramdev’s rise to fame
Televised yoga classes were Baba Ramdev’s ticket to fame; he had a following of millions and he received worldwide praise for promoting yoga and healthy living.

He successfully leveraged his fame to create a business empire. In 2006, he helped launch a company called Patanjali Ayurveda to sell herbal medicines and a few years later, the business expanded to sell almost any product. Since last year, the company has been selling a product called Coronil that it has made a number of false claims over, including that it was a WHO-approved COVID treatment.

‘Lab Leak’ Theory Gains Ground with Report of Sick Wuhan Lab Staff in 2019

On By ModernMedia
Image source: CDC/Unsplash

As reported by the Wall Street Journal, US intelligence learned three doctors at Wuhan Institute of Virology became sick with COVID-like symptoms in November 2019 and sought out hospital care. This, along with an open letter in the journal Science has prompted new calls to find out whether COVID started at that facility. 

A State Department report was issued during the last days of former President Donald Trump’s administration but officials familiar with the report did not agree on the strength of the evidence found, the Journal reported. However this new report adds more detail, and comes on the eve of a World Health Organization meeting, which will no doubt include COVID.

In March, virologist Marion Koopmans told NBC News that the illness of lab workers could be due to normal seasonal illnesses.

Earlier this year, a team from the WHO spent a month in Wuhan investigating the origin of the virus, and produced a report concluding that the virus most likely jumped from bats to people, rating a lab leak as “extremely unlikely”.

The WHO however also said it also did not have access to all the necessary information – a situation has prompted some experts to be wary of the findings and demand more investigations into the virus’s origin, including the possibility that it in fact was leaked from a lab.

November 2019 is also in line with when experts believe COVID began circulating.

For its own part, China has consistently denied that the coronavirus escaped from a lab. However, the lab has not made available its raw data or records on its work with coronaviruses in bats.

A spokeswoman for the National Security Council told the Wall Street Journal that the Biden administration has questions about the virus’, but plausible theories should be investigated by WHO.

“We’re not going to make pronouncements that prejudge an ongoing WHO study into the source of SARS-CoV-2,” the spokeswoman said. “As a matter of policy we never comment on intelligence issues.”

Lockdowns Loom as COVID Spreads Again in SA Provinces

On By ModernMedia
Image source: CDC/Unsplash

The Western Cape provincial government has said it is actively preparing for a resurgence of COVID cases while three other provinces have now declared they are in a third wave.

The province’s premier Alan Winde said in a statement on Sunday that based on current trajectories, the province is likely to officially enter its third wave two to three weeks from now.

Gauteng premier David Makhura confirmed that his province officially entered into a third wave more than a week ago. This was followed by similar declarations in the Free State and the Eastern Cape.

“The Western Cape is currently facing a resurgence as it has seen increases in its case numbers every day, over the past 12 days. While this is not yet a third wave, it is the first sign that we are moving towards one,” Winde said.

“Our guiding principle remains that no person will be denied access to life-saving medical treatment. We must make sure we have enough beds, staff and oxygen to respond effectively in the month ahead.”

He added that in the meantime South Africans should continue to follow the level 1 lockdown restrictions, adhering to social distancing and avoid social gatherings to help flatten this curve. But health experts have warned that the rise in cases could require further lockdown restrictions.

Head of the Western Cape Health Department Dr Keith Cloete told EWN that it is a national competency to put lockdown restrictions in place, but they are highly likely to appear given that the number of cases is on the increase countrywide.

Health minister Dr Zweli Mkhize has likewise warned of likely additional restrictions in South Africa due to rising COVID numbers.

He said that the government has discussed the rising numbers. “At some point we are going to have to start looking at additional restrictions,” he said.

“We are going to be recommending that there should be more focus on the size of gatherings, and look at the focus on some of the measures that were actually released when we thought the situation was much more improved.”

He highlighted the importance of trying to maintain a balance to ensure that people continue to be able to work. “We do need to send a strong message still, that people can’t be complacent.”

As of 23 May, there were 2894 new cases in South Africa and the COVID test positive rate stood at 9.86%. Data collected up to 15 May showed the highest positive rate was in the Northern Cape (24.1%), Free State (17.5%) and North West (15.1%) provinces. The percentage testing positive was <10% in all other provinces. (Source: NICD PDF, note this is a 10 MB size)

South Africa to Sign On to Digital ‘Vaccine Passport’

On By ModernMedia

Transport minister Fikile Mbalula said that South Africa will seek to join a digital ‘vaccine passport’ scheme being tested by a number of airlines.

Presenting his departmental budget speech on Friday, Mbalula said that South Africa must ensure that it joins the growing number of countries that accepts the International Air Transport Association’s (IATA) mobile travel pass for COVID vaccination.

This particular initiative was tested successfully by Singapore Airlines, and more than 20 carriers, the minister said.

“In recent months, Singapore has announced that it will accept visitors who use a mobile travel passes containing digital certificates for Covid-19 tests and vaccines,” Mbalula said.

“This makes Singapore one of the first countries to adopt this initiative. Singapore will accept the IATA mobile travel pass for pre-departure checks, where travellers can get clearance to fly to and enter Singapore by showing a smartphone application containing their data from accredited laboratories.”

The IATA’s app allows travellers to store digital information from certified labs. It will be available for download later this month. IATA aims to bring in additional changes such as QR code scanning by immigration officers.

Vaccine passports have been the subjects of debates over equitability, access and potential for abuse. However, vaccine passports are not only permissible under international health regulations, they already exist. The World Health Organization endorses certificates confirming vaccination against yellow fever for entry into certain countries. They also incentivise vaccination, a public good.

Currently, South Africa has 62 ‘major restrictions’ from other countries in place, with suspended travel, stringent requirements for entry or outright bans. Meanwhile there are 92 moderate restrictions in place on South Africa, where travel is possible subject to measures such as COVID tests on arrival.
