GENEVA - The World Health Organization insisted Monday that the AstraZeneca vaccine was still a vital tool in the global fight against the coronavirus pandemic, after South Africa delayed the start of its inoculation program over concerns about its efficacy against a virus variant.
"It is vastly too early to be dismissing this vaccine," said Richard Hatchett, who heads the Coalition for Epidemic Preparedness Innovations (CEPI), which co-leads the Covax vaccine facility with the WHO and Gavi after the AstraZeneca shot ran into a number of setbacks, including questions about its efficacy for over-65s.
"It is absolutely crucial to use the tools that we have as effectively as we possibly can," he said, speaking at the WHO's regular bi-weekly press briefing on the coronavirus pandemic.
The AstraZeneca vaccine is currently a vital part of Covax, which was set up to procure Covid-19 vaccines and ensure their equitable distribution around the world.
It accounts for almost all of the 337.2 million vaccine doses Covax is preparing to begin shipping to some 145 countries during the first half of the year, once it receives WHO authorization, which is expected next week.
But a trial at Johannesburg's University of Witwatersrand, concluded the vaccine provided only "minimal" protection against mild to moderate Covid-19 caused by the variant first detected in South Africa.
That was bad news for many poorer nations counting on the logistical advantages offered by the AstraZeneca shot.
South Africa, the continent's hardest-hit nation, had been due to start its campaign in the coming days with a million AstraZeneca doses.
However, the government decided to hold off because of the results from the trial.
"It's a temporary issue that we have to hold on AstraZeneca until we figure out these issues," Health Minister Zweli Mkhize told reporters on Sunday.
South Africa has 1.5 million AstraZeneca vaccine doses, which will expire in April.
AstraZeneca, which developed the shot with the University of Oxford, also stood by its product.
"We do believe our vaccine will still protect against severe disease," it told AFP.
A company spokesperson said researchers were already working to update the vaccine to deal with the South African variant spreading rapidly around the world.
RUSSIAN VIRUS DEATHS
Worldwide, according to official figures, the coronavirus pandemic has claimed more than 2.3 million lives worldwide out of more than 106 million known infections.
Russia has recorded a dramatic increase in mortality in 2020 fueled by the coronavirus pandemic, according to new data published by the Rosstat agency.
The figures showed that between April, when the pandemic hit Russia, and December, the country saw 162,429 coronavirus-related fatalities.
However, as of Monday, the official total released by Russia's health officials stood at only 77,068 virus deaths.
As inoculation programs are rolled out around the world, Facebook announced Monday it would ban groups that repeatedly spread false claims about the virus and vaccines in general.
The social media giant has updated a list of debunked claims about the virus and existing vaccines with the help of the WHO.
Facebook's critics, however, were unimpressed.
"Facebook has been promising to crack down on Covid and anti-vaxx misinformation for the past year," the nonprofit Center for Countering Digital Hate wrote on Twitter.
"Every time, it fails to meet these headline announcements with action."
WORSE THAN WE THOUGHT: BIDEN
Efforts are under way in the United States, the hardest-hit nation, to accelerate its mass vaccination program, which has been plagued by supply and logistics issues.
The more contagious and possibly more dangerous British variant of the virus is spreading rapidly across the country, said a new study posted online Sunday.
Although yet to be peer-reviewed, it does offer the most comprehensive look at the rise of the variant, known as B.1.1.7. Scientists led by researchers at The Scripps Research Institute analyzed half a million test samples collected across the country since last summer.
President Joe Biden, who took office last month, said his predecessor Donald Trump's handling of the pandemic "was even more dire than we thought", in an interview with CBS News Sunday.
There was less vaccine available than they had initially been led to believe, he said.
The United States is the country that has suffered most from the virus, recording more than 463,000 deaths.
Schools reopened Monday in Romania, Denmark and Austria. Museums and shops were also due to reopen in Austria.
But the Netherlands decided to extend its overnight curfew to March 2, because of the more contagious coronavirus variants circulating. The measure has already provoked riots there.
On Tuesday, an international team of experts in China investigating how the outbreak started will speak to the media in Wuhan on Tuesday, the WHO announced.
The briefing, at 4:00pm local time (0800 GMT) at a hotel in the city, will be live-streamed in English on the UN health agency's digital and social media platforms.
The first Covid-19 cases were detected in Wuhan in December 2019.
Scientists think the disease originated in bats and could have been transmitted to humans via another mammal.
But there are no definitive answers so far and top WHO officials have played down the chances of the sensitive investigation mission finding them on the first attempt.
