Office of Vaccines Research and Review (OVRR)

The Office of Vaccines Research and Review (OVRR) is a division of the U.S. Food and Drug Administration (FDA) responsible for ensuring the safety and effectiveness of vaccines. It evaluates clinical trials to assess how well vaccines work and monitors their safety once they are approved for public use. OVRR also develops guidelines and regulations to streamline vaccine development and review processes, making sure vaccines meet high standards before being made available to the public. This helps protect public health by ensuring that vaccines provide the intended benefits without unacceptable risks.
