Coronavirus: WHO backs AstraZeneca vaccine after South Africa delays jabs
- The AstraZeneca shot has run into several setbacks, including concerns about its efficacy against a Covid-19 variant, and its suitability for people over 65
- The vaccine accounts for almost all of the 337.2 million vaccine doses the WHO-led Covax scheme is preparing to begin shipping to some 145 countries
The World Health Organization insisted on 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 programme 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.
