Once you are fully vaccinated, you can start doing more
After you are fully vaccinated for COVID-19, you can resume many activities that you did before the pandemic.
CDC recommends that fully vaccinated people wear a mask in public indoor settings if they are in an area of substantial or high transmission.
Fully vaccinated people might choose to mask regardless of the level of transmission, particularly if they or someone in their household is immunocompromised or at increased risk for severe disease, or if someone in their household is unvaccinated. People who are at increased risk for severe disease include older adults and those who have certain medical conditions, such as diabetes, overweight or obesity, and heart conditions.
People are not considered fully vaccinated until 2 weeks after their second dose of the Pfizer-BioNTech or Moderna COVID-19 vaccine, or 2 weeks after a single-dose of Johnson & Johnson’s Janssen COVID-19 vaccine. You should keep using all the tools available to protect yourself and others until you are fully vaccinated.

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.
None of the COVID-19 vaccines can make you sick with COVID-19
None of the COVID-19 vaccines contain the live virus that causes COVID-19 so a COVID-19 vaccine cannot make you sick with COVID-19. Learn more Facts about COVID-19 Vaccines
