The Mercer Island School District and Costco will partner for a second Pfizer COVID-19 booster vaccine clinic this month for people ages 12 and up from 8 a.m. to noon on Sept. 24 at Northwood Elementary School, 4030 86th Ave SE.

At their Sept. 17 clinic, they delivered 899 booster doses.

“Our vaccine clinics are not successful without the awesome help of volunteers, who help check attendees in, make sure forms are filled out properly, and provide logistical support,” reads a letter to Island families from the school district communications staff.
