GENEVA (Reuters) -Current data does not indicate that COVID-19 booster shots are needed, the World Health Organization (WHO) said on Wednesday, adding that the most vulnerable people worldwide should be fully vaccinated before high-income countries deploy a top-up.
The comments came just before the U.S. government said it planned to make the booster shots widely available to all Americans starting on Sept. 20 as infections from the Delta variant of the coronavirus rise.
