I would prefer to stay away from autism (let's do asthma or another "epidemic") or just speak in general terms.
I am thinking true but simplistic.
There is a battle of two wolves inside us. One is good and the other is evil. The wolf that wins is the one you feed.
Book and herb loving mama to 1 preteen and 2 teens (when did that happen?). We travel, go to school, homeschool, live rurally, eat our veggies, spend too much time...
Children in Scandinavia or in countries (like Ireland) where there is some "Viking" ancestry seemed to be prone to narcolepsy following vaccination with Pandemrix. There certainly is a connection between the narcolepsy and the ancestry in this situation, but without the vaccine trigger there probably wouldn't have been nearly as many cases. And claims that the flu itself would trigger narcolepsy run into the Polish problem. Poland also has some interaction with the Vikings. Poland didn't use the vaccine. There was no rise in narcolepsy in Poland.
I see possible genetic epidemics with some sort of triggering situation--environmental, social or?
