November 23, 2021 update: Boosters for ages 18 and older

Anyone age 18 and older can now get a booster dose of COVID-19 vaccine if enough time has passed since their initial vaccination:

  • 6 months since second dose of Pfizer or Moderna
  • 2 months since one dose of Johnson & Johnson (J&J)

Public Health’s vaccination sites at Auburn, Kent, Bellevue Eastgate, and Downtown Seattle are using a waitlist for all booster appointments. Register for the waitlist at yourcovidvaccine.kingcounty.gov, or visit the Getting vaccinated in King County page for additional vaccine locations.

Who is eligible?

Everyone age 5 years and older is currently eligible for COVID-19 vaccination. At this time, COVID-19 vaccines are not authorized for children younger than 5 years old. Clinical trials are in process for younger children.

COVID-19 vaccine options for teens

  • Pfizer: age 5 years and older
  • Johnson & Johnson: age 18 years and older
  • Moderna: age 18 years and older

When you schedule your appointment, make sure that they offer vaccine that has been authorized for your age group.

Children under 5 not yet eligible

There are many children in King County who are not protected from COVID-19 infection. We do not know yet when children under 5 will be eligible to receive the COVID-19 vaccine.

For parents, caregivers, and families, here are resources to help you continue to keep children under the age of 5 safe.

Sector-specific guidance

What to bring to your vaccine appointment

  • Document to confirm age: state, tribe, or federal-issued identification, birth certificate, school ID or school or medical paperwork with name and date of birth can be used.

  • Wear short sleeves or loose-fitting sleeves that are easy to roll up so that you can get vaccinated in your upper arm.

  • Authorized adult consent: If you are younger than 18 years old, you may need consent from an authorized adult to get the vaccine. You can consent for yourself if you are emancipated, married to an adult, or the vaccine site determines you are a mature minor. Not all vaccine sites are able to make mature minor determinations.

  • Authorized adults who may consent for minors include:

    • Adult who has court permission to make health care decisions for you (legal guardian, custodian, out-of-home placement order)
    • Parent
    • Adult who has your parent's written permission to make health care decisions for you
    • Adult relative responsible for your health care
    • In some circumstances, a school nurse, school counselor, or homeless student liaison

    If an authorized adult will not attend the vaccine appointment with you, check with your vaccine provider about requirements for showing proof of authorized adult consent or legal emancipation.

Public Health – Seattle & King County COVID-19 Vaccine Minor Consent Form (PDF)

This form is used at Public Health – Seattle & King County vaccination sites, including the Auburn and Kent Vaccination Partnership Sites and Public Health clinics. If an authorized adult will not attend the vaccine appointment with you, this form can be used as written consent. Public Health staff can also accept verbal consent over the phone or a written note from an authorized adult. If your vaccine appointment is not at a Public Health site, check with your vaccine provider about requirements for showing proof of authorized adult consent or legal emancipation.
