Everyone 5 years+ should get a booster shot

First booster shots (5 years+)
Everyone ages 5 and older should get a booster dose to be fully protected:

  • Five months after the second dose of Pfizer or Moderna (NOTE: Immune compromised people may have more doses. Get a booster 3 months after the last dose in your primary series.)
  • Two months after one dose of J&J

Second booster shots
People who should get second booster shots of Pfizer and Moderna COVID-19 vaccines:

  • 50 years and older
  • 12 and older who are moderately or severely immunocompromised. See more information about Vaccines for Immunocompromised People on this page.

Also eligible:

  • 18 and older who received J&J for their primary and booster doses

If you are eligible, you can get the second booster at least four months after your first booster.

Vaccines for immunocompromised people

CDC recommends that anyone ages 5 and older who have moderately or severely weakened immune systems (immunocompromised) get a third dose of vaccine. The third shot is part of their initial vaccine series, not a booster.

Immune-compromised children 5-11 should also get a first booster dose. Everyone age 12 or older who is moderately or severely immunocompromised should also get two booster doses.

If your first two doses were Pfizer/Moderna:

  • Additional dose: Pfizer/Moderna, at least one month after second dose
  • First booster: Pfizer/Moderna, three months after the third dose
  • Second booster: Pfizer/Moderna, four months after first booster
  • These means five total doses

If you got J&J for your first dose:

  • Additional dose: Pfizer/Moderna, two months after one dose of J&J.
  • 1st booster: Pfizer/Moderna, two months after the additional dose
  • 2nd booster: Pfizer/Moderna, four months after 1st booster
  • These means four total doses

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.
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.

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.
