Vaccine clinical trials

Our researchers work with a simple goal in mind: Prevent infectious diseases from causing sickness and death through vaccines.

We are driven to bring vaccines to a broader set of people.

MSD has supplied more than 180 million doses of vaccines worldwide through clinical trial research and approved marketed vaccines.

There is a lot to consider when deciding whether to participate in a clinical trial. Any clinical trial includes risks, which the study doctor will review with you. Make sure you understand the risks before participating.
