How to restore credibility to the CDC’s vaccine advisory committee

Jesse Goodman, former director of CBER and former FDA chief scientist, calls for five critical changes to restore trust in the Advisory Committee on Immunization Practices.

💉If your study uses millions of patient records and finds vaccines are safe… …and your response is to block the publication? 😑 That’s not data integrity. That’s policy malpractice wrapped in anti-science spin. ⚠️ Public health runs on transparency, not selective silence. 🧪

Withdrawing from the World Health Organization was a very bad move. 👇

Maybe it’s a bad time to eliminate epidemiology in the United States.

This is a good primer on the test-negative study design if you want to know how this widely used method works: pmc.ncbi.nlm.nih.gov/articles/PMC... Main benefit is can get near real-time estimates (i.e. this vaccine against this strain), rather than low RCT (result = historical vaccine & strain)

The acting head of the CDC has canceled the publication of a study that found that the Covid vaccine sharply cut the odds of hospitalizations and emergency visits last winter www.nytimes.com/2026/04/22/u...

CDC Director is censoring CDC scientists on COVID vax effectiveness study. The stated reason is concerns about study methods. This is bogus--the test-neg design is valid and has been widely used for 15+ years. The real reason is the study results don't support RFK's anti-vax crusade. wapo.st/41JhAhb

CDC won’t publish report showing covid shots cut likelihood of hospital visits

The report, which had cleared the agency’s scientific-review process, had been delayed. It now won’t be published at all, people familiar with the decision told The Post.

I'd like to take a second to explain all the ways that this comment is disqualifying as a marker of legitimate expertise in vaccination. 🧵 www.nytimes.com./2026/04/09/h...

Acting CDC Dir is delaying publication of COVID vax effectiveness (VE) study that found high protection. He has concerns about the test-negative design (TND) but does not understand this method. It has been widely used for 15+ years & is the gold-standard for flu/COVID VE studies. 👇 wapo.st/4ccudpF

NEW: RFK Jr. is spreading doubts about vaccine safety and considering changes that could prompt manufacturers to flee the U.S. market. History has shown how plagues from the past can roar back when trust in shots — or access to them — falters.

This is a big win for evidence-based vaccine policies. ACIP can meet this week but they can’t vote to change the CDC recommendations.

I’m sure by now many of you have heard that RFK Jr.’s vaccine advisory board has “leaked” a report claiming that there is a chronic condition, similar to LongCOVID, that is caused by the COVID19 vaccine. I wanted to take some time with it before I posted, and now I have, so here comes a thread.

Growing measles outbreak in Florida, and yet somehow the Florida Dept of Health has managed to avoid mentioning vaccines. Small print suggests consulting clinics for "pre-exposure options." 🫠

Stanley Plotkin is a living legend in the vaccine world. He often attended ACIP meetings & I was lucky to meet him years ago. Kudos to @helenbranswell.bsky.social for profiling his life and accomplishments at a time when vaccines are under attack. We need his wisdom & insights more than ever. 👇

Helen Branswell 🇨🇦@helenbranswell.bsky.social · 5mo ago

Stanley Plotkin had a major hand in the development of a number of vaccines in use today; he designed the rubella vaccine. He remembers the world before widespread use of vaccines & knows what's coming as vaccine policy is rewritten & vaccine confidence is eroded. www.statnews.com/2026/03/02/s...
