Look at the itinerary of that 8 year old. That's not an immigrant child; it's a child of privilege, whose Mother has likely bought into the 'vaccines cause autism' nonsense, and a holistic lifestyle. There is absolutely NO PROOF that autism is caused by vaccines, but that flame has been fanned by Don Imus and others and gotten tons of press.
The media is claiming that more kids are getting autism, and there are folks willing to speciously make the connection between that condition and vaccinations. The truth is that it's likely kids always had some forms of autism, but they were never diagnosed as such. Many of today's cases of autism are not the profound kind that most folks associate with that description, but more are in the form of behavioral differences; shyness, difficulty dealing with other people, etc.
Vaccines can cause other damage besides autism.
