Stay Up to Date with Your COVID-19 Vaccines
What You Need to Know
CDC recommends that everyone ages 5 years and older get their primary series of COVID-19 vaccine, and everyone ages 12 years and older also receive a booster. Some people can receive two boosters.
People who are moderately or severely immunocompromised have specific COVID-19 vaccine recommendations, including recommendations for a booster. Learn more about COVID-19 vaccine recommendations for people who are moderately or severely immunocompromised.
Use CDC’s COVID-19 booster tool to learn if and when you can get boosters to stay up to date with your COVID-19 vaccines.
The following COVID-19 vaccine and booster recommendations may be updated as CDC continues to follow data related to vaccine effectiveness and safety, waning immunity, and protection against variants.
About COVID-19 Vaccines
COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and even dying—especially people who are boosted. As with other diseases, you are protected best from COVID-19 when you stay up to date with recommended vaccines.
Mixing COVID-19 Vaccine Products
CDC does not recommend mixing products for your primary vaccine series.
If you received a Pfizer-BioNTech or Moderna COVID-19 vaccine, you should get the same product for your second shot in the primary series. People eligible for a booster who are ages 18 years and older may get a different product for their booster. People eligible for a booster who are ages 12 through 17 years must get the same product (Pfizer-BioNTech) for their booster.
Timing of COVID-19 Vaccination After Infection
People who have COVID-19 should wait to receive any vaccine, including a COVID-19 vaccine, until after they recover and complete their isolation period.
Additionally, people who recently had COVID-19 may consider delaying their next booster by 3 months from when their symptoms started or, if they had no symptoms, when they first received a positive test. Reinfection is less likely in the weeks to months after infection. However, certain factors, such as personal risk of severe disease, local COVID-19 community level, and the dominant COVID-19 variant, could be reasons to get a vaccine sooner rather than later.
Talk to your healthcare professional if you have questions about when to get your next COVID-19 vaccine.
Vaccination Outside the United States
If you received COVID-19 vaccines outside the United States, whether you are up to date depends on which COVID-19 vaccine (and how many doses) you received. Learn more about when people vaccinated outside the United States are considered fully vaccinated.
Allergic Reaction to a COVID-19 Vaccine Product
If you had a severe allergic reaction after a previous dose of a COVID-19 vaccine or if you have a known (diagnosed) allergy to a COVID-19 vaccine ingredient, you should not get that vaccine. If you have been instructed not to get one type of COVID-19 vaccine, you may still be able to get another type.
Scheduling Your COVID-19 Vaccines
Find a COVID-19 vaccine or booster: Search vaccines.gov, text your ZIP code to 438829, or call 1-800-232-0233 to find locations near you.
There are several ways you can find a vaccine provider. You can get your COVID-19 vaccines at the same location, or different locations.
If you need help scheduling your second shot or your booster, contact the location that set up your previous appointment. It is never too late to get the added protection offered by completing your primary series or getting a COVID-19 booster.
Some community vaccination clinics have closed. You can get your second shot or your booster at a different location.
