TEC Brief: Anticipation of the Sept 2025 ACIP Meeting

The September ACIP meeting is scheduled for September 18-19. Based on the released agenda, we anticipate three key vaccine safety topics to surface, along with several falsehoods likely to be raised and amplified on social media:

  • The safety of the MMRV (measles, mumps, rubella, varicella) combination vaccine and its association with febrile seizures

  • Hepatitis B vaccine safety and necessity, in particular, the birth dose

  • Both pediatric and adult COVID-19 vaccine safety, focused particularly on deaths

This report provides key background on each issue, anticipates falsehoods and rumors likely to arise or be distorted, summarizes current evidence, outlines possible policy implications, and offers communication guidance for public health leaders, media, and social media influencers.

We hope this equips you—a trusted voice in health—with the tools, details, and in-depth analysis needed to drive national vaccine conversations with confidence, clarity, and authority.
