Vaccines: Safety First

Safety is a top priority while federal partners work to make a COVID-19 vaccine(s) available. Vaccines are rigorously tested using thousands of study participants to generate data and other information for the Food and Drug Administration (FDA). These results help to determine the safety and effectiveness of vaccines for mass distribution.

Visit the CDC’s website for more information about ensuring the safety of COVID-19 vaccines in the U.S. - including information about specific vaccine monitoring systems.
