None of these links prove your “never” theory. And they dont even say what vaccine is being charged as the culprit.
The first link says there is no scientific link, but x and y are both happening, so x might be the cause of y. Not scientific, not logically sound.
The second link is about a lawsuit of under 5,000 people claiming autism as a result of mercury in vaccinations, but there is nothing in the article on how the trial wound up and what type of science was used. It also happens to be from a site dedicated to non-medicinal treatment and “natural health”
The third link, also from naturalnews.com, is about how celebrities are getting behind the anti-big pharma bandwagon.
The fourth link wont open, but as the other three, is also from the suspect site.
Since you had no words you could create as a rebuttal, I take it that you are just trying to clear room for some other candidate, no matter the accuracy of your claims.
