Anyway, let me adventure some ideas:
- the boys were developping normally until they were vaccinated”
This piece of information does not tell me too much: in different diseases the boys are developing normally until the disease appears…

I order to have an opinion based on scientific facts, I would like to know:

If I study in a population big enough, two comparable groups of children, one vaccinated and other not vaccinated, which is the incidence of autism in each group?

If I study a group of autistic children, which is the ratio of (autistic non vaccinated)/(total of non vaccinated children in the whole population), and (vaccinated autistic children)/(vaccinated children in the whole population)?

Has it been demonstrated that children with autism has a higher incidence of mercury in brains than non autistic children?

Has it been demonstrated that vaccination increases mercury concentration in the brain?

I would appreciate if somebody can answer these questions.
