Two COVID vaccine doses give you important protection. But this protection drops over time and 2 doses do not protect as well against new variants like Omicron. Experts now recommend COVID boosters for almost everyone 12 years and older.
Knowing how many doses of a COVID vaccine to get can be confusing. The number of doses you need depends on your age, whether you have a weakened immune system and whether you live in a setting where you are at higher risk of getting COVID. If in question, speak to your health care provider.
