Vaccine Trials Unit

Imagine a World Without Diseases

There’s no doubt the world is desperately in need of vaccines. Seattle Vaccine Trials Unit (VTU) is leading the fight against major diseases of today such as COVID-19 and HIV/AIDS. We pursue innovative research strategies to promote heathier protected communities.

You can make an impact by joining one of our research studies for COVID-19 or HIV.

Volunteers Help Us Make Discoveries

We need volunteers to help move science toward more discoveries. Sign up now to see if you can help with one of our studies.

Coronavirus (COVID-19) Studies

Currently, we are only enrolling people with confirmed COVID-positive results from the last 30 days. Our COVID observational studies will help us gain an understanding of how the immune system works in response to COVID, and enable us to find better ways to prevent and treat the virus.

At this time all our COVID studies are observational, no medication or vaccines are given. Learn more about the Seattle COVID-Cohort Study.

HIV Research Studies

We enroll people regardless of HIV status, for HIV vaccine research studies that are coordinated by networks such as the HIV Vaccine Trials Network and the International AIDS Vaccine Initiative. The research products used in all our studies are NOT produced from live HIV or from human cells containing HIV. The study vaccines cannot cause HIV infection.

Additionally, we have a number of observational HIV studies to help us learn more about the immune system in people who have HIV but are able to naturally control the virus without taking any medications. There are no medications or vaccines given in our observational studies.

Our Invaluable Community Partnerships

Our work would not be possible without a dedicated community of collaborating organizations volunteers and donors.

A History of Collaboration — Some of our longstanding partners include African American Reach and Teach Ministries, Entre Hermanos, Gay City, POCAAN and Lifelong. Many of our HIV vaccine studies are in partnership with global networks such as the HIV Vaccine Trials Network and the International AIDS Vaccine Initiative, and many local public health officials and service organizations helped to establish a foundation for our COVID-19 research during the pandemic.

Inspired by Community — The VTU is committed to fostering and maintaining meaningful, collaborative, and mutually beneficial relationships with our community partners and study volunteers. We are especially grateful to the many people who have helped move our research forward, and for the insights and partnership of our Community Advisory Board members. We respect cultural values and diversity, and we maintain broad-minded perspectives among our staff and advisors.

Donor-powered — During the COVID-19 pandemic, Fred Hutch was able to rapidly deploy leading-edge research efforts to control the virus, thanks in part to the generous philanthropic support from individual donors and companies. Our COVID-Cohort study appreciates our local first responders and community members who joined our study and helped us to better understand how COVID impacts immune systems.

Meet the Team

As a parent, part of the reason I do this research is to create a brighter future for my son's generation. It makes my work that much more important to me.
