New omicron-specific Covid boosters for children ages 5 to 11 are "only a matter of weeks away," according to the U.S. Food and Drug Administration's vaccine chief. 

On Tuesday, Dr. Peter Marks said during an event with the Covid-19 Vaccine Education and Equity Project that he's "confident" the FDA will authorize the new shots for that age group soon, noting that vaccine manufacturers Pfizer and Moderna are in the process of submitting necessary data.
