CDC Statement on ACIP Booster Recommendations

September 24, 2021

This morning, the CDC released a statement regarding who should get a Pfizer COVID-19 vaccine booster. In an unexpected move, the CDC overruled the Advisory Committee on Immunization Practices’ (ACIP) recommendations from yesterday, when they voted 6-9 against recommending a booster for those at high risk of occupational exposure (such as healthcare workers).

These are the updated CDC recommendations:

• people 65 years and older and residents in long-term care settings should receive a booster shot of Pfizer-BioNTech’s COVID-19 vaccine at least 6 months after their Pfizer-BioNTech primary series,
• people aged 50–64 years with underlying medical conditions should receive a booster shot of Pfizer-BioNTech’s COVID-19 vaccine at least 6 months after their Pfizer-BioNTech primary series,
• people aged 18–49 years with underlying medical conditions may receive a booster shot of Pfizer-BioNTech’s COVID-19 vaccine at least 6 months after their Pfizer-BioNTech primary series, based on their individual benefits and risks, and
• people aged 18-64 years who are at increased risk for COVID-19 exposure and transmission because of occupational or institutional setting may receive a booster shot of Pfizer-BioNTech’s COVID-19 vaccine at least 6 months after their Pfizer-BioNTech primary series, based on their individual benefits and risks.
