Vaccine Safety Datalink

The Vaccine Safety Datalink (VSD) is a project by the U.S. Centers for Disease Control and Prevention (CDC) that monitors the safety of vaccines. It uses a large database containing health information from millions of individuals, both vaccinated and unvaccinated. Researchers analyze this data to detect any potential links between vaccines and health issues, ensuring that vaccines remain safe for public use. By systematically studying vaccine effects, the VSD helps to provide reassurance about vaccine safety and identifies any concerns that may need further investigation.
