Centers for Disease Control and Prevention advisers are meeting today to make their recommendations about who should get the COVID-19 booster shot and when.

Here are the conditions for booster shots set by the Food and Drug Administration: Anyone older than 65 and younger people with underlying health conditions, or if you work somewhere that puts you at high-risk of contracting COVID-19, such as health care workers, teachers, grocery store employees, those in homeless shelters and prisons.

These are FDA recommendations, but the CDC ultimately has the final say. If the CDC director signs off on the additional shots, those eligible can start getting the Pfizer boosters right away.
