I always like to go straight to the source on these things.
One question I have, though, is whether the Amish are under increased pressure to vaccinate, and whether more may be vaccinating, but not admitting it to the researchers.
What else could change their results? (Am I correct that their rates are increasing, but that they used to be lower than the rest of the population?) Maybe GMO contamination of crops?
Epidemiology is a challenging puzzle.
