Delaying second Covid vaccine shots can be ‘very risky,’ says former FDA director
- It's risky for the U.K. to delay second doses of vaccines because efficacy data was based on a specific dosing schedule, said former FDA director Norman Baylor.
- "I understand some of the rationale to do this, but again, it's not really data driven," said Baylor. "It's a very risky venture because if it fails, you're in worse shape."
- The U.K.'s decision was reluctantly and conditionally endorsed by health advisors in the country.
