As the number of new COVID-19 cases reached a historic high in the last two weeks, vaccine boosters have become a growing concern. Although adults have been able to get boosters since Nov, children and teens under 16 haven’t.

On Jan. 3 the Food and Drug Administration (FDA) authorized that all recipients of the Pfizer vaccine who are 12 or older can get a booster shot five months after their second vaccine dose.

If you received a Moderna or Johnson & Johnson vaccine, you still must be 18 or older to get a booster. Moderna has a six-month waiting period between vaccine and booster, while Johnson & Johnson has a two month waiting period.

Both the Centers for Disease Control and Prevention (CDC) and FDA recommend all Americans receive all doses of the COVID-19 vaccine.
