Those who received the Moderna vaccine should get a booster dose if they are 18 or older and at least 5 months have passed since their second primary series dose. 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.
Second booster shots using an mRNA vaccine are recommended for those who are:
- Age 12 and older with weakened immune systems and received their initial booster at least 4 months ago
- Age 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
- Age 50 and older and received their initial booster dose at least 4 months ago
