It's Lindsay Smith Rogers, producer of public health on call. As 2025 winds down, we want to say

thank you for listening, contributing, and sticking with us through another year of massive

We've also launched a brand new Instagram account at Public Health Pod, where you'll find highlights, quotes, and behind-the-scenes moments, as well as ways to tell us about what topics you want to hear next.

You can also send us your questions and voice memos anytime at

If you have questions or ideas for us, please send an email to Public Health Question at jh.edu.

That's Public Health Question at jhu.edu for future podcast episodes.
