Aedes, Ritalin might not be the drug of choice where you live, but it is called for in many school districts.
As far as additives go, I'm specifically speaking about ; sucrose, HFCS, dyes, aspartamine and hormones. All of them are added to food. The EU will no longer accept our beef that has hormones.
I'm not including thousands of other chemicals that affect everyone;

The cited article on the autism-vaccination link is from the CDC. They're always behind the curve. They don't pander to big pharma quite as much as the FDA, but they're still big drug pushers.
You need to do more reading on the latest research.
I drove from Fairbanks to Lima, drove around Mexico, Asia, OZ, Europe, middles East etc. I've been in the clinics and hospitals and all the rest. I visited friends in Tumaco, Colombia. It's a hell-hole for malaria. Yes, DDT did kill mosquitoes. Now the bay in Tumaco has a strata of DDT. It poisons the crustaceans and , of course, enters the food chain.
Tumaco is also the center of the drug eradication efforts. They kill a lot more than coca.
The number one killer in the world is
diarrhea. It doesn't matter if a person has cholera or whatever, it's the diahrrea that kills them. I travelled around India by road,,, even went to Benares. I got giardia , missed hepatitus. Sailed on the Nile in a felluca, got something, missed shistosomiasis. So far I've missed Lyme, and West Nile.
Modern medicine is very impressed with itself. The truth is that it is very limited. You can't vaccinate for dirty water. I'm sure that vaccination has some value. It isn't the problem-free cure all that big pharma would have you believe.
You need to do more complete research.
