Status: The COVID-19 vaccine is here. Two vaccines have been authorized for emergency use by U.S. Food & Drug Administration (FDA). Both vaccines have also passed independent review by medical experts in the Scientific Safety Review Workgroup, as part of the Western States Pact (English only). See our FAQs for more information.
About the vaccines
Pfizer-BioNTech COVID-19 vaccine: The vaccine is authorized for emergency use in persons aged 16 years and older. This is a two-dose vaccine, given 21 days apart. Clinical trial data show the vaccine is 95 percent effective at preventing COVID-19 infection starting seven days after the second dose. Individuals will not be considered fully protected until one to two weeks after they receive the second dose. The clinical trials revealed no major unanticipated adverse events. This vaccine arrived in Washington on December 14.
Moderna COVID-19 vaccine: This vaccine is authorized for emergency use in individuals aged 18 years and older. This is a two-dose vaccine, given one month apart. Clinical trial data shows the vaccine is about 94 percent effective after two doses. No serious safety concerns were found. We expect to get our first shipment of this vaccine the week of December 21.
Washington State COVID-19 Vaccination Plan
The Centers for Disease Control and Prevention (CDC) required all states and territories to turn in an interim plan for COVID-19 vaccine distribution on Oct. 16, 2020. These plans are living documents and will change over time as we learn more about the vaccines and figure out the most equitable way to protect people.
