Booster doses for people who have received 2 doses of Pfizer vaccine.
At this time, only people who have had 2 doses of the Pfizer vaccine who meet certain conditions are eligible for a booster dose.
- The following people should receive a booster dose of Pfizer vaccine 6 months or later following their 2nd dose of Pfizer vaccine:
- people aged 65 years and older
- people aged 18 years and older who live in long-term care settings
- people aged 50–64 years who have underlying medical conditions or who experience social and economic risks that place them at increased risk for COVID-19
- The following people may consider receiving a booster dose of Pfizer vaccine at least 6 months after their 2nd dose of Pfizer vaccine, based on their individual benefits and risks:
- people aged 18–49 years with underlying medical conditions
- people aged 18–64 years at increased risk for COVID-19 exposure and transmission because of their occupational or institutional setting*
If you have questions about the risks and benefits or whether a booster dose is right for you, talk with your doctor or healthcare provider.
*Examples of institutional settings include healthcare, schools, group homes, prisons, and shelters. The CDC currently defines occupations at increased risk for COVID-19 as:
- First responders (healthcare workers, firefighters, police, congregate care staff)
- Education staff (teachers, school staff, daycare workers)
- Food and agriculture workers
- Manufacturing workers
- Corrections workers
- U.S. Postal Service workers
- Public transit workers
- Grocery store workers
Booster doses are currently only available to people who already received 2 doses of Pfizer vaccine because Pfizer is the only vaccine that has been authorized by the FDA for booster doses. People in the recommended age groups who received the Moderna or J&J/Janssen vaccine will likely need a booster shot, and more data on the effectiveness and safety of these booster shots are expected in the coming weeks.
- The booster dose must be a Pfizer vaccine. To search for a location that offers the Pfizer vaccine, use the search by “Vaccine Type” filter below.
- When you go to the location, take proof of vaccination such as your CDC white card or digital vaccination record (see Vaccination Records webpage for details, including how to get your digital record) to show that you received 2 doses of Pfizer vaccine at least 6 months ago.
- If you attend a site run by Public Health, you will be asked to sign a self-attestation form: English | Español (Other languages)
