The CDC has approved mix and match booster doses for those who are eligible for a booster. This means that a person can receive a booster of a COVID-19 vaccine that is different than the COVID-19 vaccine they received for their primary series or initial booster.

Initial booster shots are recommended for those who are:

• 12 and older and completed their primary vaccination series of Pfizer at least 5 months ago
• 18 and older and completed their primary vaccination series of Moderna at least 5 months ago or completed their primary vaccination of Johnson & Johnson at least 2 months ago

If you are age 12-17, you must receive the Pfizer booster as it is the only booster approved for this age group. For primary and booster vaccination, people should receive an age-appropriate mRNA vaccine (Pfizer or Moderna). The Johnson & Johnson vaccine is authorized for anyone age 18 and older if no other approved vaccine is available. Bring your COVID-19 Vaccination Record Card to your appointment.

The CDC has authorized a second booster shot using an mRNA vaccine for those who are:  

• 12 and older with weakened immune systems and received their initial booster at least 4 months ago
• 18 and older and received the Johnson & Johnson vaccine for their primary series and received a Johnson & Johnson booster dose at least 4 months ago
• 50 and older and received their initial booster dose at least 4 months ago
