Individuals ages 12 and older are eligible for a Pfizer-BioNTech bivalent booster dose at least 2 months after their previous booster dose or 2 months after completing their initial primary vaccine series.

Additional Dose Information

What is the difference between a booster shot and an additional dose?

Booster:
 A booster shot is administered when a person has completed their vaccine series and protection against the virus has decreased over time.  

Additional Dose:
The additional dose of an mRNA-COVID-19 vaccine is intended to improve immunocompromised people’s response to their initial vaccine series because they were not able to respond appropriately to the first and second shot.

Who is eligible for an additional dose?

  • If you received Pfizer-BioNTech: People age 5+ who are moderately or severely immunocompromised should get an additional primary shot of Pfizer-BioNTech COVID-19 vaccine. Given 28 days after 2nd shot.

  • If you received Moderna: People age 18+ who are moderately or severely immunocompromised should get an additional primary shot of Moderna COVID-19 vaccine. Given 28 days after 2nd shot.

  • If you received Johnson & Johnson’s Janssen: No additional primary shot is recommended at this time

 

CDC recommends the additional dose for people who have

  • Been receiving active cancer treatment for tumors or cancers of the blood
  • Received an organ transplant and are taking medicine to suppress the immune system
  • Received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system
  • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
  • Advanced or untreated HIV infection
