Merck cares deeply about helping the world be well. We strive to improve health for others in the future by developing new drugs and vaccines that treat and prevent disease. Clinical trials are an essential part of this process. We are thankful for the thousands of volunteers — patients and healthy persons — who participate in clinical trials.
