TOKYO/CAIRO -- Advanced nations hold hundreds of millions of excess coronavirus vaccine doses at risk of expiring before they can be given to people in developing countries that have had greater difficulty in sourcing shots.
About 100 million doses purchased by or promised to Group of Seven and European Union members are to expire by year-end, even after taking booster shots into consideration, an analysis by U.K. research firm Airfinity shows. A total of around 240 million will come within two months of expiring, a point at which they become logistically difficult to send to emerging economies.
