COVID-19 vaccination is a safer way to help build protection
- Get vaccinated regardless of whether you already had COVID-19. Evidence is emerging that people get better protection by being fully vaccinated compared with having had COVID-19. One study showed that unvaccinated people who already had COVID-19 are more than 2 times as likely than fully vaccinated people to get COVID-19 again.

- 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.
People who have a condition or are taking medications that weaken their immune system may not be fully protected even if they are fully vaccinated. They should continue to take all precautions recommended for unvaccinated people, including wearing a well-fitted mask, until advised otherwise by their healthcare provider.
