• COVID-19 vaccines are safe and effective
  • Everyone 6 months and older is now eligible to get a free COVID-19 vaccination
  • Get Vaccinated and Stay Up to Date!
    • Fully vaccinated means a person has received their primary series of COVID-19 vaccines.

      Graphic of Why You Should Stay Up to Date

COVID-19 Variants

Viruses are constantly changing to create new types of the virus called variants. COVID-19 vaccines used in the United States continue to protect against severe disease, hospitalization, and death from known circulating variants. They may not be as effective in preventing infection from these variants. CDC will continue to monitor vaccine effectiveness to see what impact, if any, variants have on how well COVID-19 vaccines work in real-world conditions.

Updated Boosters Are Recommended

CDC recommends that people ages 5 years and older receive an updated (bivalent) booster if it has been at least 2 months since their last COVID-19 vaccine dose, whether that was:

  • Their final primary series dose, or
  • An original (monovalent) booster

People who have gotten more than one original (monovalent) booster are also recommended to get an updated (bivalent) booster.

Vaccine Information for People Who are Immunocompromised

If you are moderately or severely immunocompromised (have a weakened immune system), you are at increased risk of severe COVID-19 illness and death. Additionally, your immune response to COVID-19 vaccination may not be as strong as in people who are not immunocompromised.
