TULALIP — Snohomish County’s sixth mass vaccination site is set to open in Tulalip.

The drive-thru site at Boom City, operating by appointment only, will offer Moderna shots Tuesday, the Snohomish County Vaccine Taskforce announced in a news release.

Later in the week, the clinic will switch to the Johnson & Johnson vaccine.

Currently, vaccine eligibility is limited to the state’s Phase 1A and 1B categories. That includes anyone 60 and older, people 16 and older who are pregnant, people 16 and older with two or more health conditions, some essential workers and more.

The county’s other five mass vaccination sites, in Everett, Lynnwood, Arlington and Monroe, will continue operating this week, the news release said. The locations are listed, along with the type of vaccine provided and registration links, at www.bit.ly/snocovaccine.

People who do not have internet access, need language assistance, or have other barriers to online registration, can reach the county’s call center at 425-339-5278 between 8:30 a.m. and 4:30 p.m. Monday through Friday.

Additionally, if appointments are full at the mass vaccination sites, people can sign up for a waitlist for an individual day.

If there is a cancellation or additional doses are otherwise available at the site that day, people on the waitlist will be notified. The waitlist does not roll over, so people will need to sign up again for the next day.
