Thank you for your interest in the CASCADIA study!

The CASCADIA study will help us learn more about how often COVID-19 occurs among adults and children. The study will also help us learn how well COVID-19 vaccines work to prevent COVID-19 infection and illness.

Study activities include weekly nasal swabs and annual blood draws.

We are looking for people to join our study who are:

  • 6 months to 49 years of age, and
  • live in or around Portland, Oregon or Seattle, Washington. Your home address must be in our study area as our drivers are only able to pick up swabs from certain zip codes.
