Few months ago, WHO mentioned that there were not enough of dozes to reach out to some African countries. If these African countries still need them, it would be waste to throw the vaccine away. The best way is to evaluate and test out whether the shelf life of vaccine can be extended for use as first and second boosters for them. Better have something to standby for them than nothing for them. These countries should be given infrastructural help to build chilled storage vault rooms to keep vaccines chilled and storage them under lock and key.
