June begins with the rain. As hurricane season arrives, we’re following the ripple effects that weather leaves behind—from infectious disease threats that emerge after storms, to the ticks and mosquitoes that thrive in the conditions rain creates. Along the way, we’ll pause for a quiet moment beneath a summer shower before returning to one of nature’s most persistent pests. This month, we’re exploring how the forces that shape our environment also shape our health, often in ways we don’t notice until the clouds have passed.
What My
Listeners Say
I am a scientist and I found this to be highly informative and beautifully explained. I highly recommend this even if you know some about the COVID-19 vaccines.
Grace-V, PhD
This was an excellent explanation for mRNA. I am pleased to add that after having listened, I felt completely confident getting my covid vaccine. Can't wait for more episodes.

A fantastic explainer on measles by The Infectious Dose. I can't recommend this one loudly enough. Take a listen!
Judy Minkoff, PhD
I'm a layperson, not a scientist and definitely not a virus or vaccine expert. I felt substantially more informed about the vaccines after listening to this information.
Mike D from Detroit
This was great! Thanks for answering my question in such detail. Also, the RFKjr debunk session was tops!
Patrick Passarelli, MD
Blogs and Podcasts Worth Your Time
Check out these blogs and podcasts on virology and infectious disease by real scientists conveying accurate information! These are just some I really like, they are not paying me to be here. They don't even know they're here. Hopefully they don't mind.
