No, you don't understand the point I was making (read the last sentence in my post). Your examples detract from your point rather than strengthen it. The scientific community embraced those two theories to some degree pretty quickly^* because more and more evidence came out demonstrating their veracity. On the other hand, more and more evidence is coming out demonstrating that the glut of anti-vaccination claims are simply not true. The notion that vaccinations represent a significant risk or even a level of risk that outweighs the benefits has been overwhelmingly rejected by the scientific community on the basis of evidence. There has certainly been no good evidence demonstrating a causal link to autism that I'm aware of. In 20 to 30 years, we will only be more certain that the anti-vaccination movement is intellectual tripe.

*In fact, Einstein's theory of relativity was arguably pretty much immediately accepted by the majority of the scientific community. It is extremely disingenuous that you are portraying as something that came entirely out of left field and that it was an uphill battle to get people to accept it. People like Poincare, Lorentz, and Minkowski had been suggesting ideas like the constancy of the speed of light in all frames of references along with the weird implications like length contraction and time dilation for years. There are even some people who suggest that Einstein's work did not give enough credit to others and was quite possibly entirely derivative. The fact that most of Einstein's peers immediately set about extending his ideas and verifying them experimentally demonstrates that they were seen as having merit.
