How well flu vaccines protect public health

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Lauren Meyers explains what the 2022-2023 influenza season taught us about the effectiveness of flu vaccines.

In this episode, we cover:
•[00:00] Introduction
•[01:16] Computational epidemiologist Lauren Meyers introduces the health and hospitalization burden of seasonal influenza.
•[01:47] She defines vaccine effectiveness.
•[02:37] Meyers describes the features of the 2022-2023 flu season.
•[04:05] She describes how the researchers estimated the hospitalizations prevented by vaccination.
•[05:11] Meyers tells how vaccination of young adults protected adults over 65 years of age.
•[06:56] She describes the takeaways of the study for future flu seasons.
•[08:08] Meyers lists the caveats and limitations of the study.

Tune into PNAS Science Sessions for a direct line to the people shaping modern science. Produced by PNAS, this podcast offers more than just summaries of published research; it’s where you hear the candid, often personal stories behind the headlines. Each episode features concise conversations with the researchers themselves-from emerging voices to established Academy members-alongside the policymakers whose decisions are informed by this work. You’ll get a genuine sense of the questions that drive these experts, the unexpected hurdles they face in their labs and field studies, and why their findings matter right now. The scope is deliberately wide, reflecting the interdisciplinary nature of science itself, covering discoveries that range from microscopic processes to planetary-scale phenomena. This isn't about dry lectures, but about capturing the human endeavor of investigation. For anyone curious about how science actually unfolds and wants to understand the context of breakthroughs as they happen, this podcast serves as an essential, engaging resource. It connects the dots between a published paper in a prestigious journal and the real-world implications that ripple out from it.
