Why do some folks think that the CDC had hidden evidence that the hepatitis B vaccine increased a child’s risk of autism?
The usual suspects…
Did the CDC Have Hidden Evidence That the Hepatitis B Vaccine Increased the Risk of Autism?
In this case, Secretary RFK Jr is once again bringing up a conspiracy theory about an old hepatitis B study.
“And CDC did that study in 1999, they brought in a team of, of scientists under a Belgian researcher named Thomas Verstraeten.
And they looked at the data, they looked at children who had received the hepatitis vaccine within the fir their first 30 days life. And those children to children who had received the vaccine later were not at all. And they found an 1,135% elevated risk of autism among the vaccinated children. And it shocked them. They kept the study secret and they manipulated it through five different iterations to try to bury the link.”

Kennedy was corrected when he brought it up on Joe Rogan, and was corrected again when he recently brought it up on The Tucker Carlson Show.
Far from being trying to bury the link, Verstraeten conducted a planned second phase of the study and could not confirm the positive findings of the first phase.
“The CDC screening study of thimerosal-containing vaccines was perceived at first as a positive study that found an association between thimerosal and some neurodevelopmental outcomes. This was the perception both independent scientists and antivaccine lobbyists had at the conclusion of the first phase of the study. It was foreseen from the very start that any positive outcome would lead to a second phase.”

That’s it.
But that hasn’t kept anti-vaccine influencers from running with it - laundering this old bit of propaganda across their sites.
Are you surprised?

And let’s not forget that these antivaxers are unable to convert odds ratios into percentages.
None of them can do math, not a single one.
There is no data at the CDC that is trustworthy for the last 50 years. If you are a medical doctor and you’re not practicing alternative medicine yet, you are compromised too. I have no interest in allopathic only doctors. It’s a business model. It’s not a healing model.
