On January 4, 2022, the CDC updated recommendations regarding the interval between a primary series of the Pfizer/BioNTech COVID-19 vaccine and a booster dose. The CDC recommended shortening the interval from 6 months to 5 months for those who received the Pfizer/BioNTech COVID-19 vaccine. The booster interval recommendation for people who received the J&J vaccine (2 months) or the Moderna vaccine (6 months), has not changed.
One day later, the Advisory Committee on Immunization Practices (ACIP) recommended a single Pfizer/BioNTech COVID-19 vaccine booster dose for persons aged 12 – 15 years at least 5 months after primary series under the FDA’s emergency use authorization (EUA). This recommendation follows closely after the FDA announced an expanded EUA for a single booster dose to individuals 12 years of age and older who have completed a primary series with Pfizer/BioNTech COVID-19 vaccine on January 3, 2022. This expands the use of the Pfizer/BioNTech COVID-19 vaccine as a booster which was previously indicated only for individuals 16 years and older.
