How do I know if the COVID-19 vaccine is safe?
All COVID-19 vaccines were tested in clinical trials involving tens of thousands of people to make sure they meet safety standards and protect adults of different ages, races, and ethnicities. There were no serious safety concerns. These trials were very similar to trials done for other licensed vaccines, but were done more quickly due to the urgent need to reduce illnesses during the pandemic. CDC and the FDA will keep monitoring the vaccines to look for safety issues after they are authorized and in use.
