Student gets a COVID-19 vaccine

We want to create a safe and healthy learning environment for your child. The COVID-19 vaccine can protect your child from the Delta variant and is the best way to prevent the spread of COVID. That’s why we’re hosting multiple vaccination clinics for students and families, in partnership with UW Medicine and HealthPoint.
