The World Health Organization gave emergency use approval to AstraZeneca’s COVID-19 vaccines on Monday, meaning distribution can start to poorer countries starved of doses to fight the pandemic.
The AstraZeneca-Oxford jab forms the bulk of batches being lined up through Covax, the global programme aimed at procuring and shipping out vaccines equitably around the world, regardless of wealth.
It is only the second COVID-19 jab to have received WHO authorisation, after the Pfizer-BioNTech vaccine.
“The WHO today listed two versions of the AstraZeneca-Oxford COVID-19 vaccine for emergency use, giving the green light for these vaccines to be rolled out globally through Covax,” the UN health agency said in a statement.
The two versions given the seal of approval are being produced by the Serum Institute of India (SII), and by SKBio in South Korea.
Separate reviews were needed for each production process, although the vaccine is the same.
“Countries with no access to vaccines to date will finally be able to start vaccinating their health workers and populations at risk, contributing to the Covax facility’s goal of equitable vaccine distribution,” said WHO assistant director general Mariangela Simao.
“But we must keep up the pressure to meet the needs of priority populations everywhere and facilitate global access. To do that, we need two things — a scale-up of manufacturing capacity, and developers’ early submission of their vaccines for WHO review.”
337.2 million doses
The organization’s emergency use listing procedure assesses the quality, safety and efficacy of COVID-19 vaccines, and is a prerequisite for vaccines in the WHO co-led Covax facility.
AstraZeneca vaccines from India and South Korea made up almost all of the initial 337.2 million doses lined up for Covax’s first wave of distribution, which is set to get moving in late February.
Some 145 participating economies are set to receive enough doses to immunise 3.3 percent of their collective population by mid-2021.
The first wave includes 240 million SII AstraZeneca doses; 96 million South Korean AstraZeneca doses; and 1.2 million Pfizer doses.
Both vaccines require two injected doses.
“We now have all the pieces in place for the rapid distribution of vaccines,” WHO director-general Tedros Adhanom Ghebreyesus told a press conference.
Simao added: “There’s no need to panic and no need for countries to go buying in the market, because they’re going to pay more.”
