Information About COVID-19 (Novel Coronavirus)

COVID-19 Vaccines at Seattle Children’s

Seattle Children’s is providing COVID-19 vaccination services to all members of our community, and our patients and their caregivers. We are only administering the Pfizer BioNTech COVID-19 vaccine and are not currently offering any other vaccines. 

The Pfizer BioNTech COVID-19 vaccine is:

  • Approved for people 5 to 15 years old for first and second doses under an Emergency Use Authorization
  • FDA approved for people 16 years and older for first and second doses (the vaccine has been renamed to “Comirnaty” for this age group)
  • Approved as a third dose for people 5 years and older who are moderately to severely immunocompromised under an Emergency Use Authorization
  • Approved for people 12 years and older for first and second booster doses under an Emergency Use Authorization

First and Second Doses

Seattle Children’s provides first and second doses of the Pfizer COVID-19 vaccine to people ages 5 years and above.

  • It is recommended that the second dose be given 21 days after the first dose for people who are moderately or severely immunocompromised, adults ages 65 years and older, and others who need rapid protection due to increased concern about community transmission or risk of severe disease.
  • An 8-week interval may be optimal for some people ages 12 years and older, especially for males ages 12-39 years, to reduce risk of heart issues.
  • If you received your first dose at Seattle Children’s, your second dose appointment is automatically scheduled for you through our scheduling system for 3 weeks after you receive the first dose.
  • If you want to receive your second dose at longer interval (can be up to 8 weeks), please cancel your automatically assigned second dose and select a new appointment date and time.
  • We can provide a second dose to people 18 years and older who received a first dose of Janssen vaccine who are moderately to severely immunocompromised or recommended by their provider.

Second Doses Only

Seattle Children’s can provide a second dose for people who received their first dose at another location.

To request a second dose appointment when you did not receive your first dose at Seattle Children’s, email COVIDCommunitySupport@seattlechildrens.org.

Third Dose

Seattle Children’s provides a third dose of the Pfizer COVID-19 vaccine to qualifying people ages 5 and above who are moderately or severely immunocompromised and who had a second Pfizer or Moderna vaccine dose at least 28 days ago.

To qualify for the third dose of the vaccine, you must meet 1 of the following criteria as set forth by the Centers for Disease Control and Prevention (CDC). Your primary care provider may also recommend that you receive the third dose because you are considered moderately or severely immunocompromised.

  • You are undergoing active cancer treatment for tumors or cancers of the blood.
  • You received an organ transplant and are taking medicine to suppress the immune system.
  • You received a stem cell transplant within the last 2 years or are taking medicine to suppress the immune system.
  • You have a moderate or severe primary immunodeficiency disorder (includes conditions like DiGeorge syndrome or Wiskott–Aldrich syndrome).
  • You have advanced or untreated HIV infection.
  • You are taking high-dose corticosteroids or other medicines that may suppress your immune response.

Note: You will not be required to show proof that you are moderately or severely immunocompromised at the time of the vaccination.

First Booster Dose

Seattle Children's provides a first booster dose of the Pfizer COVID-19 vaccine to people who are:

  • 12 years and older and who received two doses of the Pfizer vaccine at least 5 months ago
  • 18 years and older and who received two doses of the Moderna vaccine at least 5 months ago
  • Immunocompromised people who are 5 years and older who received a third Pfizer or Moderna vaccine dose at least 3 months ago
  • 18 years and older and who received one or two doses of the Janssen (Johnson & Johnson) vaccine

Second Booster Dose

Seattle Children's provides a second booster dose of the Pfizer COVID-19 vaccine to people who are:

  • 12 years and older and who are moderately to severely immunocompromised and received their first booster dose of the Pfizer or Moderna vaccine at least 4 months ago
  • 50 years and older and who received their first booster dose of the Pfizer, Moderna, or Janssen vaccine at least 4 months ago

Prior to Scheduling Your Appointment

  • Confirm it is the right time to receive the vaccine:
    • Talk to your primary healthcare provider about any questions or concerns related to the vaccine and your medical needs.
  • Make sure that you are well enough:
    • You will not be provided the vaccine if you are in the 2-week exposure/quarantine timeframe, which is
      • Within 6 feet of another individual with known or suspected COVID-19 illness without a mask and eye protection for 15 minutes or greater
  • You will not be provided the vaccine if you are in the 2-week isolation timeframe with the COVID-19 illness, which is:
    • Two weeks since a positive COVID-19 test or onset of symptoms
  • At the time of your vaccine, we will also ask some screening questions to confirm this is the right time for you or your child to receive the vaccine. The vaccine clinical team will not be able to advise you if any underlying health conditions could stop you from receiving the vaccine or should be considered before you receive it
