- Reposted by Megan Culler Freeman MD, PhDThe CDC changed the universal vaccine schedule & no longer recommends Rotavirus Hepatitis A & B Meningitis Influenza RSV I’ve cared for previously healthy kids who died from RSV, influenza and meningitis. We all are going to be caring for a lot more now. In our already overflowing hospitals

- I’m starting to think we should do a #medEd series on ‘recognizing vaccine preventable illnesses’. Anyone interested in coorganizing? #idsky #pedsid @pidsociety.bsky.social @febrilepodcast.com @idsainfo.bsky.social
- Reposted by Megan Culler Freeman MD, PhDThere's a lot of focus right now on a person's right to choose whether to be vaccinated. But the risks falling vaccination rates pose to individuals — especially young babies, the elderly & the immunocompromised — need to be part of that discussion. www.statnews.com/2025/12/23/v...

- Reposted by Megan Culler Freeman MD, PhDA picture is worth a 1000 words. The birth dose of hepatitis B vaccines in the USA eliminated perinatally acquired hepatitis B infection from over 20,000 cases a year before the vaccine was introduced to <20 cases a year. The gaslighting by the current members ACIP is obscene, unethical and cruel.

- Excited to be a part of this inaugural class! 🎉 My very first paper was in #JVirology and I’ve been a fan ever since. 🦠
- I couldn’t WAIT to get nirsevimab for my baby. He barely noticed when RSV circulated in his class. It was amazing. Starkly different from when my older child had RSV as an infant and nearly needed to go to the hospital.

The conclusion is clear and unambiguous: There’s no link between vaccines and autism." -Dr. Susan Kressly, AAP President on recent changes to the CDC's website
- Honored to be selected for @socpedresearch.bsky.social and always looking forward to what my team will do next. 🦠

This will hit health systems hard especially rural hospitals and hospitals in underserved areas that sponsor these visas through waiver programs.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come. But, this is the WH's *proposed* budget.
