Boosters Now Available at Main Campus

The Centers for Disease Control and Prevention (CDC) has removed qualifying criteria to expand who can get the COVID-19 vaccine booster doses for extended immunity. Seattle Children’s now is able to administer booster doses under an emergency use authorization to any individual who is 18 years and older and has:

  • Received two doses of either the Pfizer or Moderna vaccine at least six months ago
  • Received the single-dose Janssen vaccine at least two months ago

Appointments are required and available from 7:30 a.m. to 5 p.m., Monday through Saturday, at our main campus.

If families wish to schedule a COVID-19 vaccine for their child(ren) but find no appointments are available on our scheduling portal, they can contact us at and we will get them in. Cancellations are frequent, so there is always space opening up.

Please note: We only offer the Pfizer vaccine. We don’t have supplies of Moderna or Janssen. For more information about COVID-19 vaccination at Seattle Children’s, please visit our vaccine page.

Antibody Infusion for COVID-19 Patients

To request monoclonal antibody infusion for a patient, please contact the Infectious Disease team at Seattle Children’s first. You can reach Infectious Disease by emailing Do not refer patients directly to Infusion Services until you have approval from Infectious Disease. The infusion clinic is able to provide these infusions to pediatric patients age 12 years and older (at least 40 kg) who meet eligibility criteria (see seventh page: “Monoclonal Antibody Products for Mild-Moderate COVID-19”). Our space is limited; we have one negative airflow room available each day, which has been in high demand recently.
