Summary

Influenza is rising rapidly across the U.S., and headlines about H3N2 and “new variants” are everywhere. In this episode, I break down what the data actually show, what’s driving this flu season, what H3N2 subclade K really means, how well the flu shot is holding up (spoiler- it's doing fine!), and what matters most for protecting your family. Using current CDC surveillance data and real-world vaccine effectiveness, we put this season into clear perspective. I also share how our household is thinking about and managing play dates, preschool and traveling during an active flu season.
