The guidance on COVID-19 boosters has changed again. And with every change and with active internet disinformation campaigns, it gets more difficult for many people to trust what they are hearing.

On this episode of Petrie Dish, host Bonnie Petrie speaks with Dr. Tracey Baas of Texas Biomedical Institute about timing, mixing and matching, who should be getting it, and more.

Editor's note: Texas Biomed is among Texas Public Radio's financial supporters. That didn't, of course, play any role in our decision to talk with Dr. Baas.
