COVID Vaccine Info


There is a phased plan for administering COVID vaccine and it will take time before most of the public is vaccinated. In the meantime, people should maintain other preventive measures.

When are appointments posted for the mass vaccination sites?

  • Appointments for the Edmonds and Everett sites, when doses are available, will open for a week at a time, typically posting over the weekend or early in the week (Monday or Tuesday).
  • Appointments for the Arlington and Monroe sites, when doses are available, will open for one or two days at a time, posting around 2 p.m.

Please note that exact timing for opening appointments may vary from the target schedule listed above based on vaccine availability.

Tools for Patients 

Second doses

According to CDC guidelines, individuals should receive two doses of the Moderna vaccine at least 28 days apart. The Pfizer vaccine should be two doses at least 21 days apart. 

The second dose should be administered as close to the recommended interval as possible. However, if it is not feasible to adhere to the recommended interval, the second dose of Pfizer-BioNTech and Moderna COVID-19 vaccines may be scheduled for administration up to 6 weeks (42 days) after the first dose. There are currently limited data on efficacy of mRNA COVID-19 vaccines administered beyond this window. If the second dose is administered beyond these intervals, there is no need to restart the series.

You'll receive a vaccination card at the appointment for your first dose. Save the card and take a photo on your phone in case you lose it. This has information on the brand you received for your first dose, and you may be required to show that record when you get your second dose.

If you received your first COVID vaccine at the Snohomish County Vaccine Taskforce sites in Monroe or Arlington, please watch for an email arriving within a few days before or after your target date for a second dose. The email will include a registration link just for people who received their first dose at the mass vaccination site and need to schedule their second dose. 

Vaccine supply is still limited, and we do not know exactly how many second doses we will have in the coming weeks. This means that you may not be able to register for an appointment on your target date, but don’t worry. The available appointments will still be within the acceptable window for your second dose.

If you need to provide or update/confirm your email address, please complete this quick contact form:
