Who Really Believes in Pseudoscience? Pro-Vaxxers or Anti-Vaxxers?

You know, I wish provaxxers looked critically at their own studies that they believe to prove their own point.

For example, the idea that vaccines are not associated to [insert your favorite adverse reaction here], is currently not strongly supported by any of available science that I’ve seen.

Let’s take the most popular one of all, that vaccines are not associated to autism.

If you were to try to support that with studies, you’ll likely be linking study after study that shows:

MMR is not associated to autism
Thimerosal is not associated to autism

Here’s the problem with those studies in terms of design: you’re comparing a vaccinated population vs a vaccinated population, but using the MMR as a variable.

As an exaggeration, let’s assuming the following vaccination histories of the case and control group:

Case Group
Hep B x 3
DTaP x 4
Hib x 3
Pneumococcal x 3
Polio x 3
Influenza x 1
Varicella x 1
Hep A x 1
MMR x 1

Control Group
Hep B x 3
DTaP x 4
Hib x 3
Pneumococcal x 3
Polio x 3
Influenza x 1
Varicella x 1
Hep A x 1

The only difference being that the case group has been vaccinated for MMR and the control group has not.

When you find that the autism rate between both groups is statistically insignificant, you then conclude that MMR is not associated to autism.

Fair enough, so as long as the PROPER CONTEXT of this conclusion is established, that is, if you’re going to be vaccinating anyways, then the MMR isn’t going to pose any more significant risk.

But for the life of me, I DO NOT UNDERSTAND how people use these studies designed in this manner to conclude that VACCINES are not associated to autism.

You want to attack Exley and Shaw, fine. But if you’re going to do that, you should be just as upset with the multitude of studies that don’t even come CLOSE to answering the question, are vaccines (as a whole) associated to [adverse reaction]?

The vast majority of vaccine safety science is designed similarly to this, so to say that you have science on your side when there are no real studies to support that conclusion shows to me who really believes in pseudoscience.
