Countries move ahead with vaccine booster plans despite WHO plea

London — French President Emanuel Macron said Thursday his country would join the handful of nations that plan to offer a third dose of the coronavirus vaccine to elderly and vulnerable people, despite the World Health Organization calling on Wednesday for a hold on booster shots until at least the end of September.

WHO chief Dr. Tedros Adhanom Ghebreyesus appealed for countries that were further along in their vaccination programs to wait until September to distribute third doses to allow for at least 10% of the population of every country to be vaccinated. "I understand the concern of all governments to protect their people from the Delta variant. But we cannot accept countries that have already used most of the global supply of vaccines using even more of it," Tedros said.
