South Sudan, for instance, recently destroyed nearly 60,000 doses it received from Covax; Malawi destroyed 20,000. Neither were able to distribute their entire allotments before the vaccines expired. Kenya, with more than 50 million people, received over a million doses from Covax in early March, but had used less than one-fifth by late April. The Ivory Coast similarly distributed less than a quarter of the over 500,000 doses it received in late February, raising fears that doses will expire before they are used. The problem goes beyond lower-income countries. More than 600,000 Covax-provided AstraZeneca vaccines sit in Canada at risk of spoilage, while Canadians debate whether it is safe to use them. Vaccinations can begin to confer meaningful protection in under 14 days. Freed from freezers, these vaccines could have saved many lives in Peru, India or Brazil, where the pandemic is raging.
