Getting vaccinated prevents severe illness, hospitalizations, and death. Unvaccinated people should get vaccinated and continue masking until they are fully vaccinated. With the Delta variant, this is more urgent than ever. CDC has updated guidance for fully vaccinated people based on new evidence on the Delta variant.

COVID-19 Vaccines Are Safe

  • COVID-19 vaccines were developed using science that has been around for decades.
  • COVID-19 vaccines are not experimental. They went through all the required stages of clinical trials. Extensive testing and monitoring have shown that these vaccines are safe and effective.
  • COVID-19 vaccines have received and continue to undergo the most intensive safety monitoring in U.S. history. Learn more about how federal partners are ensuring COVID-19 vaccines work.

COVID-19 Vaccination is a Safer Way to Help Build Protection

  • Get vaccinated regardless of whether you already had COVID-19. Studies have shown that vaccination provides a strong boost in protection in people who have recovered from COVID-19,.
  • Learn more about the clinical considerations for people were treated for COVID-19 with monoclonal antibodies or convalescent plasma, or history of multisystem inflammatory syndrome in adults or children (MIS-A or MIS-C).
  • COVID-19 is still a threat to people who are unvaccinated. Some people who get COVID-19 can become severely ill, which could result in hospitalization, and some people have ongoing health problems several weeks or even longer after getting infected. Even people who did not have symptoms when they were infected can have these ongoing health problems.

Immunity After COVID-19 Vaccination

  • There is still a lot we are learning about COVID-19 vaccines and CDC is constantly reviewing evidence and updating guidance. We don’t know how long protection lasts for those who are vaccinated.
  • What we do know is that COVID-19 has caused very serious illness and death for a lot of people.
  • If you get COVID-19, you also risk giving it to loved ones who may get very sick. Getting a COVID-19 vaccine is a safer choice.
  • At this time, there are limited data on vaccine effectiveness in people who are immunocompromised, including those taking immunosuppressive medications. Learn more about the considerations for fully vaccinated people who are immunocompromised.
