How can the vaccine help end COVID?

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

Shaquita Bell, MD explains how more people getting the COVID vaccines can help stop the spread of coronavirus.

So, we don’t need a vaccine to be at 100% to make an infection die. Essentially, to get rid of coronavirus we need as many people as possible to get the vaccine. And then the infection can’t jump from person to person to person. It doesn’t have anywhere to go. It’ll go away. So, a really good example of that is smallpox. When we started the smallpox vaccine trial, it’s not 100%, if you could still get smallpox even after you were vaccinated. But so many people became vaccinated that we eradicated, we got rid of smallpox entirely and it doesn’t exist anymore. And it’s not because every single person has been vaccinated. I haven’t been vaccinated because I was born after the vaccine, but it’s because there was not enough hosts for that infection to survive. It’s really cool, science! It’s great!
