Am I eligible for a coronavirus booster shot?

Every fully vaccinated person in the United States age 12 or over is eligible to get a coronavirus booster shot as long as enough time has passed since their last vaccine dose, according to federal regulators.

The Centers for Disease Control and Prevention on Nov. 19 boiled its long list of criteria down to just two: age and date of vaccination. If your second dose of the Moderna or Pfizer-BioNTech vaccines was at least five months ago, you are eligible for a booster. Adults who received the Johnson & Johnson vaccine are eligible after two months.

A majority of U.S. adults and a growing number of children 5 and over are vaccinated. The CDC recommends a booster for those 12 and older to supercharge the immune system’s ability to fight off the coronavirus and protect against the most serious effects of covid-19.

CDC recommendations allow boosters of any of the three vaccines that are authorized by the Food and Drug Administration, and consumers can choose a booster of a different vaccine than the one they received originally.

Many states had already expanded access in hopes of staving off a surge in covid cases during the holidays.
