We have another study showing that there is no connection between vaccines and autism:

There is no link between receiving a number of vaccines early in life and autism, researchers said on Friday.

In a study slated to appear in The Journal of Pediatrics, researchers said there is no association between receiving “too many vaccines too soon” and autism, despite some fears among parents around the number of vaccines given both on a single day and over the first 2 years of life.

As many as one in 50 U.S. school-age children have been diagnosed with autism, up 72 percent since 2007.

Researchers from the Centers for Disease Control and Prevention and Abt Associates analyzed data from children with and without autism spectrum disorder (ASD), according to a statement from the journal.

Researchers examined each child’s cumulative exposure to antigens, the substances in vaccines that cause the body’s immune system to produce antibodies to fight disease, and the maximum number of antigens each child received in a single day of vaccination, the journal’s statement said.

The antigen totals were the same for children with and without ASD, researchers found.

Not surprising.

In the normal course of growing up, a child is exposed to hundreds, possibly thousands, of new antigens a day, the idea that adding a dozen or so to that would be received through a series of vaccinations would “cause” autism is ludicrous.

Of course, the antediluvian thinking of the anti-vax crowd has real consequences: we have seen increases in outbreaks of previously nearly vanished childhood diseases resulting from a loss of herd immunity.
