Covax vaccine programme to deliver 237 mn doses to 142 nations by end-May

The timeline for the delivery of doses, made by AstraZeneca and by India's Serum Institute, will be split into separate two-month schedules, Covax said in a statement, with the first in February-March and the second in April-May. "These timelines are dependent on a variety of factors including national regulatory requirements, availability of supply, and fulfillment of other criteria such as validated national deployment and vaccination plans," the statement said.
