How do we know the COVID vaccines are safe?

Health care workers answer questions about the COVID-19 vaccines.

Edith Bracho-Sanchez, MD explains that the COVID vaccines went through rigorous testing to ensure safety.

We in this country are really privileged to have a very good, very robust system, that looks at vaccine safety. So, before any vaccine goes on the market there’s been months of tests to make sure that it is safe. Those months before vaccine goes on the market are meant to find common side effects that could be serious. And based on those results, we say, “Yes” or we say “No.” After a vaccine is approved it doesn’t mean we stop looking, right? We keep looking. And when we give it to a lot of people, millions and millions and millions of people, then we’re going to find the potential one-in-a-million side effect that could happen. When that happens, the right thing to do is to stop and say, “What happened here?” So, everyone knows how to treat this if they see it. And so, we don’t lose lives. And so, we don’t lose hope, and we don’t lose our faith in the safety of vaccines.
