COVID-19 Booster Eligibility

Anyone 18 and older who received 1st and 2nd dose Pfizer COVID-19 vaccines may be eligible for a booster 6 months after their 2nd dose.

People Who SHOULD Get A Booster Shot

People aged 65 years and older and adults 50–64 years with underlying medical conditions SHOULD get a booster shot of Pfizer-BioNTech vaccine. The risk of severe illness from COVID-19 increases with age, and can also increase for adults of any age with underlying medical conditions.

Residents aged 18 years and older of long-term care settings SHOULD get a booster shot of Pfizer-BioNTech vaccine. Because residents in long-term care settings live closely together in group settings and are often older adults with underlying medical conditions, they are at increased risk of infection and severe illness from COVID-19.

People Who MAY Get A Booster Shot

People aged 18–49 years with underlying medical conditions MAY get a booster shot of Pfizer-BioNTech vaccine based on their individual benefits and risks. Adults aged 18–49 years who have underlying medical conditions are at increased risk for severe illness from COVID-19. However, that risk is likely not as high as it would be for adults aged 50 years and older who have underlying medical conditions.

People aged 18–49 years who have underlying medical conditions MAY get a booster shot after considering their individual risks and benefits. This recommendation may change in the future as more data become available. Those who are unsure about whether to get a vaccine or booster or have questions should consult a healthcare provider.

People aged 18–64 years at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting MAY get a booster shot of Pfizer-BioNTech vaccine based on their individual benefits and risks.

Adults aged 18–64 years who work or reside in certain settings (e.g., health care, schools, correctional facilities, homeless shelters) may be at increased risk of being exposed to COVID-19, which could be spreading where they work or reside. Since that risk can vary across settings and based on how much COVID-19 is spreading in a community, people aged 18–64 years who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting MAY get a booster shot after considering their individual risks and benefits. This recommendation may change in the future as more data become available. Those who are unsure about whether to get a vaccine or booster or have questions should consult a healthcare provider.

Occupations at increased risk for COVID-19 exposure and transmission include front line essential workers and health care workers as previously detailed by the CDC*
