Booster doses of COVID-19 vaccine

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)

You can choose a different vaccine for your booster if you want a different type (for example, getting a Pfizer booster after the Moderna vaccine, or a Moderna booster after the J&J vaccine). The J&J vaccine has a low risk of a serious blood clotting disorder, especially for women under age 50. Other vaccines that do not have this risk are available.

Protection from the initial doses decreases over time. The booster shot “boosts” immunity and maximizes protection. It’s especially important for older adults (50 and older) and other high-risk populations (with underlying medical conditions or who work or live in high-risk settings) to get the extra protection from a booster shot.

COVID-19 vaccine for children ages 5-11

Children can now get the Pfizer vaccine formulated for those aged 5-11. The Pfizer vaccine that is given to adults and adolescents cannot be used for children ages 5-11. Please check Vaccine Locator, visit the Getting vaccinated in King County page, or contact a clinic to make a vaccine appointment for ages 5-11. Some providers may have limited appointments for children.

COVID-19 vaccine is always free. Everyone ages 5 and older can get a vaccine. Ages 5-17 can get Pfizer ONLY, ages 18+ can get Pfizer, Moderna or J&J. Learn more about vaccination for youth at kingcounty.gov/vaccine/youth

Cost of vaccine

There is no cost to you for the COVID-19 vaccine, regardless of immigration or health insurance status. The vaccine will be covered by Medicare, Medicaid and most private insurance, and the cost of the vaccine will be covered for people who are uninsured.

COVID-19 vaccination providers cannot:

  • Charge you for the vaccine.
  • Charge you directly for any administration fees, copays, or coinsurance.
  • Deny vaccination to anyone who does not have health insurance coverage, is underinsured, or is out of network.
  • Charge an office visit or other fee to the recipient if the only service provided is a COVID-19 vaccination.
  • Require additional services in order for a person to receive a COVID-19 vaccine; however, additional healthcare services can be provided at the same time and billed as appropriate.

COVID-19 vaccination providers can:

  • Seek appropriate reimbursement from the recipient’s plan or program (example: private health insurance, Medicare, Medicaid) for a vaccine administration fee. However, providers cannot charge the vaccine recipient the balance of the bill.
  • Seek reimbursement for uninsured vaccine recipients from the Health Resources and Services Administration’s COVID-19 Uninsured Program.
Vaccine safety is a priority

Safeguards to ensure that vaccines meet standards for safety and effectiveness include:

Clinical trials

COVID-19 vaccines must go through rigorous clinical trials in which many thousands of study participants receive the vaccine. The Food and Drug Administration (FDA) evaluates the scientific data from these studies to determine the safety and effectiveness of each vaccine. FDA relies on analysis and recommendations from an advisory group of independent scientists and experts, the Vaccines and Related Biological Products Advisory Committee (VRBPAC). VRBPAC meetings are open to the public.

If a vaccine meets the FDA's safety and effectiveness standards, the FDA can make the vaccines available for use in the U.S. by traditional licensure or emergency use authorization.

After the FDA makes its determination, a second independent advisory body of immunization experts, the Advisory Committee on Immunization Practices (ACIP), will review the vaccine's safety and effectiveness data. They will make recommendations to the CDC with guidance for healthcare providers and the public about the use of the vaccine.

Vaccine Safety Monitoring

After any vaccine is authorized for use, including COVID vaccines, multiple safety monitoring systems are in place to watch for possible side effects. If an unexpected serious side effect is detected, experts work as quickly as possible to determine whether it is a true safety concern. This serves as an ongoing evaluation of safety even after the clinical trials are completed. For COVID-19 vaccine, the CDC and FDA have expanded safety monitoring systems to carefully evaluate safety in real-time and make sure the COVID-19 vaccines are as safe as possible.

Only licensed and trained health professionals can give vaccinations

Only individuals who are licensed and trained to administer vaccines will be able to provide vaccination. Once the vaccine is more widely available to the general public, many different types of healthcare providers will provide vaccine in order to make the vaccine accessible for all who are interested in receiving it. These providers may administer vaccine both in clinics and hospitals and at more mobile or pop-up events in the community.

Important to continue COVID-19 safeguards
  • A safe and effective vaccine against COVID-19 is a major break-through. But vaccine alone won't end the pandemic right away.

  • Not everyone is vaccinated, and more contagious variants are spreading. Protective measures – including wearing masks as required in schools, hospitals, on public transportation, and other settings, improved indoor ventilation, and getting tested as needed – continue to be crucial to prevent hospitalizations and deaths from COVID-19.

  • The good news is that once you’re fully vaccinated, you can start doing many things again that stopped because of the pandemic. Learn more on the Getting Vaccinated in King County page.
Vaccine progress and strategy

Our aim in King County is to efficiently and equitably vaccinate as many eligible King County residents as possible in order to suppress the spread of COVID-19 and minimize the impact of the pandemic on our community.
