COVID-19 Vaccine Booster Dose

The Centers for Disease Control and Prevention (CDC) and the Oregon Health Authority (OHA) recommend a booster dose of the COVID-19 vaccine for everyone 5 years or older, for all authorized brands of the vaccine available in the United States. A booster is an additional dose of a vaccine given after the full series has been completed to increase the effectiveness of the vaccine.

If you received Pfizer

It is recommended that everyone 5 years or older receive a booster dose at least five (5) months after completing the primary vaccination series. Yourth 5-17 years old must receive a Pfizer booster. Anyone 18 and older may choose to receive any brand of available COVID-19 vaccine authorized in the United States.

If you received Moderna

It is recommended that everyone 18 years or older receive a booster dose at least five (5) months after completing the primary vaccination series. You may choose any brand of available COVID-19 vaccine authorized in the United States for your booster.

Johnson & Johnson Vaccine Booster

It is recommended that everyone 18 years or older receive a booster dose at least two (2) months after their initial dose. You may choose any brand of available COVID-19 vaccine authorized in the United States for your booster. The CDC and OHA recommends your booster dose be a mRNA vaccine. For those individuals who have only received a primary and a booster dose of Johnson & Johnson, a second booster is authorized: this booster must be a Pfizer or Moderna (mRNA) vaccine.

Choosing your COVID-19 booster dose

For those 18 years or older, you may choose any brand of available COVID-19 vaccine authorized in the United States for your booster. Some people will prefer to stick with their original vaccine type, while others may prefer their booster to be a different brand.


 

Additional Booster Dose

The CDC and the OHA have updated their recommendations to allow people ages 50 or older and immunocompromised individuals ages 12 and older to be eligible for another booster of an mRNA (Pfizer or Moderna) COVID-19 vaccine. The second booster can be administered at least 4 months after the initial booster. 

In addition, adults who received a primary vaccine and booster dose of Johnson & Johnson’s COVID-19 vaccine at least 4 months ago may now receive a second booster dose using an mRNA COVID-19 vaccine.

These updated recommendations acknowledge the increased risk of severe disease in certain populations including those who are elderly or over the age of 50 with multiple underlying conditions, and allows them to seek an additional booster dose to increase their protection against severe disease from COVID-19. Please speak with your medical provider if you are unsure if an additional booster dose is the right choice for you.


 

Additional Dose for Immunocompromised Individuals

A third dose of Pfizer/Comirnaty or Moderna vaccine is recommended for individuals 5 years old or older who have moderately to severely compromised immune systems. Individuals should talk to their healthcare provider about their medical condition and whether getting an additional dose is appropriate for them. Learn more about this recommendation here

For those who received the Johnson & Johnson vaccine, a second primary dose is recommended at least 28 days after the first dose. This additional dose should be a Pfizer or Moderna vaccine.

For more information about the difference between a booster shot and a third dose, please see this FAQ from the OHA.

Booster Dose for Immunocompromised Individuals

The Centers for Disease Control and Prevention recommends everyone age 5 and older, including people who are immunocompromised and received a third dose of Pfizer or Moderna, get a booster dose three months or more after their third dose. Youth 5-17 years old are only eligible to receive the Pfizer vaccine. Learn more at https://govstatus.egov.com/or-oha-booster-covid-19-vaccine.

For those who received the Johnson & Johnson vaccine, a booster dose of either a Pfizer or Moderna vaccine is recommended two months after the additional primary dose. If you have already received a booster, it is instead recommended you receive an additional booster at least two months after your last dose.
