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 administering the Pfizer BioNTech and Moderna COVID-19 vaccines.

Pfizer COVID-19 Vaccines

The Pfizer BioNTech COVID-19 vaccine is:

  • Approved for children 6 months to 4 years old for first, second, and third doses under an Emergency Authorization
  • 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 5 years and older for a first booster dose under an Emergency Use Authorization
  • Approved for people 50 years and older, 18 years and older if received Janssen for first dose and first booster, or those 12 years and older who are moderately to severely immunocompromised for a second booster under an Emergency Use Authorization.

    First, Second and Third Doses for Ages 6 Months – 4 Years Old

    Seattle Children’s provides first, second and third doses of the Pfizer COVID-19 vaccine to children 6 months to 4 years old, starting on June 21.

    • It is recommended that the second dose be given 21 days after the first dose.
    • It is recommended that the third dose be given 2 months after the second dose.
    • If you received your first dose at Seattle Children’s, your second and third dose appointments are automatically scheduled for you through our scheduling system. Your second dose will be scheduled for 3 weeks after you receive the first dose, and your third dose will be automatically scheduled for you for 2 months after your scheduled second dose.

    First and Second Doses for Ages 5 Years and Above

    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.

    Third Dose for Immunocompromised for Ages 5 Years and Above

    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 1 month ago.

    People are considered to be moderately or severely immunocompromised (have a weakened immune system) due to several types of conditions and treatments. Examples include:

    • Have been receiving active cancer treatment for tumors or cancers of the blood
    • Received an organ transplant and are taking medicine to suppress the immune system
    • Received chimeric antigen receptor (CAR)-T-cell therapy (a treatment to help your immune system attach to and kill cancer cells) or received a stem cell transplant (within the last 2 years)
    • Moderate or severe primary immunodeficiency (such as DiGeorge syndrome, Wiskott-Aldrich syndrome)
    • Advanced or untreated HIV infection
    • Active treatment with high-dose corticosteroids or other drugs that may suppress their immune response.

    Talk to your healthcare provider about COVID-19 vaccination. Your provider may refer you for COVID-19 vaccination based on your medical condition.

    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 for Ages 5 Years and Above

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

    • 5 years and older who received two doses of the Pfizer vaccine at least 5 months ago
    • 18 years and older who received two doses of the Moderna vaccine at least 5 months ago
    • Moderately to severely 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 who received one or two doses of the Janssen (Johnson & Johnson) vaccine at least 2 months ago
    • Received an international COVID-19 vaccine at least 5 months ago

    Second Booster Dose for Ages 12 Years and Above

    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 or Moderna vaccine
    • Are 18 and older and received Janssen vaccine for their first dose and first booster and it has been 4 months since their first booster.

    Moderna COVID-19 Vaccines

    We offer the Moderna COVID-19 vaccine at our hospital main campus location only, starting on June 21. This vaccine is approved for:

    • Children 6 months to 5 years old for first and second doses under an Emergency Authorization.
      • It is recommended that the second dose be given 28 days after the first dose.
      • If you received your first dose at Seattle Children's, your second dose appointment is automatically scheduled for you through our scheduling system for 4 weeks after you receive the first dose.
    • This is the only age group for which we carry the Moderna COVID-19 vaccine. We do not have any Moderna vaccines available for 6 years and above.

    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
