The World Health Organization is evaluating 15 vaccines and says it could list several of them for emergency use within weeks, according to a new guidance document published by WHO on Wednesday.
The organization is part of a global initiative called COVAX to ensure rapid and equitable access to Covid-19 vaccines around the world.
The only vaccine in the document it already has listed for emergency use is the Pfizer/BioNTech Covid-19 vaccine, which is also authorized in the United States.
The WHO document says that a decision around emergency use for AstraZeneca's Covid-19 vaccine is anticipated by the end of January, at the earliest. The same vaccine, produced in South Korea by SK Bioscience, could be listed for emergency use by the second half of February at the earliest.
By mid-February, the AstraZeneca vaccine manufactured by Serum Institute of India could also be listed for emergency use, according to WHO documents.
The document also estimates that Moderna's Covid-19 vaccine, which already has been authorized in the United States, could get an emergency use listing by the end of February.
By March at the earliest, China’s Sinovac Covid-19 vaccine and Sinopharm Covid-19 vaccine could be listed for emergency use. The Johnson & Johnson Covid-19 vaccine, which is administered as a one-dose shot, could be listed for emergency use by May at the earliest, notes the WHO document.
