I wasn't familiar with that story, so I read a brief summary. That anecdote mostly predates the modern scientific method, taking place in the 1840s. PNAS, for example, wasn't founded until 1915, and double-blind testing didn't begin formally until 1950[0]. Anecdotes like that are exactly what informs our modern scientific method. Medical research doesn't occur in the form of politicians spreading thoroughly debunked misinformation on YouTube. There is no legitimate research being suppressed here. Real research occurs in well-established journals, with well-understood and justified research methodologies. There is still room for improvement, of course, in both research and practice. But these days, the incentives are mostly well aligned to prevent that kind of story happening, and get the best results out to people as soon as possible. You will have a hard time coming up with a modern example of overlooked medical research that is well supported by research.

Why, though? What have you gotten out of that experience? Are you an expert in epidemiology and immunology, to evaluate the studies yourself? You can't "decide for yourself" in the field of medical research. You need years of education and a career to even begin to operate in that arena. You need to rely on experts and the established methods and organizations to do the research and synthesize best practices. If you really want to contribute to the conversation about immunology and vaccine safety, you need to go get a medical degree and hop into the established field of research. If you can't do that (I sure can't!), then you need to trust real medical experts. Politicians on YouTube are not real medical experts.
RFK Jr isn't proselytizing some new, well-supported medical theory rejected by the establishment. He's just spouting complete nonsense that has been debunked to an absolutely ludicrous degree. Spreading this misinformation has a real, human cost. Vaccine refusal is directly responsible for tens of thousands of preventable deaths in the US annually[1,2]. Spreading medical misinformation has real, serious consequences. It is absolutely correct for platforms that care about public health to refuse to provide people like RFK Jr a megaphone.
