The latest round of round of COVID shots are now available, but with each round of new boosters,

uptake is lower.

My hope is that as time progress, people become more and more comfortable with the idea of getting

seasonal vaccinations for COVID-19 along the flu.

It's Wednesday, September 18th, and you're listening to Science Friday.

I'm Cyphrai producer Shoshana Bucksbaum.

In the past few weeks, the latest versions of the COVID-19 vaccine

have been approved from Badera, Pfizer, and Novovax. It's been almost four years

since the release of the original MR&NA vaccine and since then there have been

several rounds of boosters. It's sometimes hard to keep up. Just 22% of eligible

adults got the last round of updated vaccines and just 14% of kids got theirs.

That's according to the latest data from the CDC.

As we ride out the end of this crushing summer COVID wave, we thought that right about now might be a good time for a refresher on COVID vaccines.

So we put out a call to our audience on social media and newsletters to answer your most pressing questions about them.

Here's Sci-Fi producer Kathleen Davis with more.

Joining me to help answer those questions and more is my guest.

Dr. Kismikia Corbett Iler, Assistant Professor of Immunology

and Infectious Diseases at Harvard's TH Chan School of Public Health, based in Cambridge, Massachusetts.

Thank you so much for being here today.

Thank you so much for having me.

Well, we are very excited to have you here.

So I think at this point, it's very possible that most people listening to this have gotten COVID at least once over the past few years.
