SciFri producer Kathleen Davis talks with Dr. Kizzmekia Corbett-Helaire, assistant professor of immunology and infectious diseases at Harvard’s T.H. Chan School of Public Health to help answer our listeners’ top questions about the updated COVID-19 vaccines.

This Q&A, which includes questions from our audience members, has been adapted from our interview with Dr. Kizzmekia Corbett-Helaire. It has been edited for clarity and brevity.

If I’ve already had COVID and it wasn’t so bad, why should I even bother with this new booster?

There’s always a chance that COVID-19 will cause more than the sniffles, or that you could end up in the emergency room—especially for older people. Why take that chance when you have the option to go to your local CVS and, in many cases, get a free vaccine that has been proven to decrease your chances of more severe disease?

My hope is that as time progresses, people become more comfortable with the idea of getting seasonal vaccinations for COVID-19 along with flu.

Is the new COVID-19 vaccine one shot?

Yes.
