WASHINGTON -- As soon as Tuesday, the U.S. Food and Drug Administration could authorize COVID-19 booster shots for Americans over 50 years old, two officials familiar with the matter told ABC News, though the fourth shots are likely to be only offered and not formally recommended.
After FDA's expected authorization early this week, the Centers for Disease Control and Prevention will give guidance on how to implement it in pharmacies and doctors offices around the country, as the process has gone throughout the pandemic. "I would not be surprised, even though there's no guarantee, that we would require an intermittent boosting, somewhat similar to what we see about the requirement of a flu shot each year," Fauci said during an appearance on the BBC's 'Sunday Morning' program.
The U.S. does have the funds to supply everyone over 50 years old with a booster shot this spring, Health and Human Services leaders told ABC News.
