COVID-19 Booster Vaccines

Updates as of November 19, 2021:

  • To align with California guidance.

COVID-19 Booster vaccines are recommended following the primary vaccination series for specific populations, as outlined below.

Who:

A Booster dose of the Pfizer or Moderna vaccine is recommended if you:

  • Received your second dose at least six months ago, and
  • Are age 18 or older

A Booster dose of the Johnson & Johnson vaccine is recommended if you:

  • Received your first dose of the Johnson & Johnson vaccine at least two months ago, and
  • Are 18 or older

What:

COVID-19 Booster doses help keep immunity strong and increase protection against COVID-19. You may receive the Booster dose of your choice, following completion of your primary vaccination series.

When:

Booster doses can be received after completion of the initial vaccine series, which consists of 1 dose of the Johnson & Johnson vaccine or 2 doses of the Pfizer or Moderna vaccines. The following timeline is recommended for individuals who received Pfizer, Moderna or Johnson & Johnson COVID-19 vaccines: 

  • Pfizer: at least 6 months after completion of the initial vaccine series
  • Moderna: at least 6 months after completion of the initial vaccine series
  • Johnson & Johnson: at least 2 months after completion of the initial vaccine series

California is actively administering Booster doses to those in the recommended populations.

Where:

Boosters are available through all current channels, including healthcare providers, clinics and neighborhood pharmacies. Californians can visit the My Turn webpage (MyTurn.ca.gov) or call 833-422-4255 to make an appointment or find a walk-in vaccine clinic near you.

Why:

All COVID-19 vaccines continue to provide significant protection against severe illness, hospitalization, and death. However, certain populations are seeing a slight decrease in vaccine effectiveness against infection. Booster doses of vaccines are very common. They are part of most childhood and adult vaccine series to ensure a person maintains optimal immunity against infection from a disease.
