Pfizer Booster Dose Recommendations

Pfizer Booster Dose Update

The Iowa Department of Public Health has shared the CDC's recommendations for Pfizer booster doses that were adopted yesterday and today.

CDC recommends:

  • 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.
  • 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.

These recommendations are ONLY for those who originally received two-dose series of Pfizer’s COVID vaccine in the primary series, at least 6 months ago.

Booster doses might be recommended in the future for those who received COVID vaccines manufactured by Moderna or Janssen (Johnson & Johnson), or those who received a different mRNA vaccine for each dose in the primary series, but ACIP did not address these situations.
