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.

Pfizer COVID-19 Vaccines

We offer the Pfizer BioNTech mRNA COVID-19 vaccines at our hospital campus in Seattle, Odessa Brown Children’s Clinic (OBCC) Othello, and South Clinic in Federal Way.

These vaccines are:

  • Approved for children 6 months to 4 years old for first and second doses under an Emergency Authorization.
  • Approved for people 5 to 11 years old for first and second doses under an Emergency Use Authorization.
  • FDA approved for people 12 years and older for first and second doses (the vaccine has been renamed “Comirnaty” for this age group).
  • Approved for people 5 to 11 years old who have a health condition or are undergoing a treatment that makes them moderately to severely immunocompromised for a third dose under an Emergency Use Authorization. Please Note: You will not be required to show proof of medical condition at the time of the vaccination.

Moderna COVID-19 Vaccines

We offer the Moderna mRNA COVID-19 vaccine at our hospital campus in Seattle and South Clinic in Federal Way. The Moderna vaccines are not available at OBCC Othello.

This vaccine is:

  • Approved for children 6 months to 5 years old for first and second doses under an Emergency Authorization.
  • Approved for children 6 months to 5 years old who have a health condition or are undergoing a treatment that makes them moderately to severely immunocompromised for a third dose under an Emergency Authorization. Please Note: You will not be required to show proof of medical condition at the time of the vaccination.
    • If your child turns 6 years old between their first and second doses, the CDC recommends that the second dose be the Moderna vaccine developed for children 6 to 11 years old.
    • You will need to cancel your appointment at Seattle Children’s and schedule a second dose at an alternate site.

Second and Third Doses

  • Patients' initial vaccination can range from a single dose to a 3-dose series depending upon their age, immune system and type of vaccine for the first dose.
  • If you received your first dose at Seattle Children’s, your second dose is automatically scheduled for you at the applicable interval.
  • If your child (age 6 months to 4 years old) received their second dose of the Pfizer vaccine at Seattle Children’s, their third dose is automatically scheduled for them at the applicable interval.
  • If you or your child received your first dose or second dose of the primary series at another facility or pharmacy, please email COVIDCommunitySupport@seattlechildrens.org and we will help you to schedule an appointment with us.

Moderna and Pfizer Bivalent Boosters

The Pfizer-BioNTech mRNA Bivalent booster is available at our hospital campus, Seattle Children’s South Clinic in Federal Way and OBCC Othello by appointment. The Moderna mRNA Bivalent booster is offered at our hospital campus in Seattle and South Clinic in Federal Way. The Moderna vaccines are not available at OBCC Othello.

The booster is:

  • The bivalent booster is different than the Pfizer or Moderna COVID-19 vaccine.
  • The COVID-19 bivalent boosters combine the original COVID-19 vaccine with BA.4 and BA.5 variants. That means the bivalent booster will help protect against COVID-19 and COVID-19 caused by the recent Omicron variant.

Who is Eligible for the Bivalent Booster?

The current Pfizer and Moderna mRNA COVID-19 vaccines are no longer authorized for use as boosters in individuals 5 years and older. People should receive the bivalent booster who are:

  • 5 years and older at least 2 months after their primary vaccination or most recent booster may receive the Pfizer bivalent booster.
  • Children 6 months through 4 years of age who have not yet begun their three-dose primary series of the Pfizer-BioNTech COVID-19 Vaccine or have not yet received the third dose of their primary series will now receive the updated (bivalent) Pfizer-BioNTech COVID-19 vaccine as the third dose in their primary series following two doses of the original (monovalent) Pfizer-BioNTech COVID-19 Vaccine.
  • Children 6 months through 5 years of age who received the original (monovalent) Moderna COVID-19 Vaccine are now eligible to receive a single booster of the updated (bivalent) Moderna COVID-19 Vaccine two months after completing a primary series with the monovalent Moderna COVID-19 Vaccine.

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 10 days 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 10 days isolation timeframe with the COVID-19 illness, which is:
    • 10 days 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.
