The CDC has refused to study the autism rate in vaccinated vs. unvaccinated kids, because they are a captive agency of vaccine manufacturers. The former head of the CDC is now the head of Merck vaccines, the largest US vaccine manufacturer. CDC officials have been disrespectful, bumbling fools when required to testify before Congress.
The CDC is reluctant to compare autism rates in unvaxed vs. vaxed because it will likely show the same thing as the following study and survey, a huge increase in autism risk in the vaccinated. Of course such data will indict the CDC and expose their responsibility for creating the biggest epidemic in US history: Vaccine-induced autism.
