Why the Senate's 'Most Important Vaccine Study Ever' Was Never Published
The fatal flaws that made this study unpublishable
jakescottmd.substack.com
A US senate subcommittee was told this unpublished vaccine study was 'the most important ever.' Henry Ford Health now confirms why it was never published: it failed scientific standards.
Here's what's actually wrong with the study:

Does aluminum in vaccines harm kids?
Aluminum in vaccines doesn’t build up or harm kids. Studies show it’s safe, quickly leaves the body, and doesn’t cause chronic health problems.

RFK Jr. told NYT he personally ordered CDC to change its vaccine-autism guidance. This is extraordinary; cabinet secretaries shouldn't override scientific consensus. The fingerprints of his 20-year crusade are all over the new CDC page. 🧵
For years, Kennedy’s organizations used the DQA from the outside to try to force CDC to walk back its vaccine assurances. Now he’s in charge of HHS and he’s using the same law from the inside to declare that decades of evidence-based language was a DQA violation.

As public health citizens, we rely on agencies like the CDC for science-based guidance. But last night’s change to its “Vaccines & Autism” page - now hinting at a possible vaccine link - deeply undermines that trust. When credible institutions shift in ways that echo anti-vax rhetoric, we all lose.
