What is it Like to Participate?
Based on my personal experiences, I encourage people to look into the clinical trials at the VRC. You really cannot ask for nicer or more dedicated and knowledgeable staff than those at the VRC, and they appreciate all of their volunteers. Give it a shot and be a part of something truly important!
