Vaccine safety studies don’t use a control group. I say this again: vaccine safety studies don’t use a control group.
Even if Vaxxed had shown a 9,000% increase in black males getting autism after vaccination, even if Vaxxed showed the evidence that 99% of people vaccinated got autism, this could still be fairly described as “not evidence of anything,” and the vaccine companies could testify in Congress to that effect and have no fear of being prosecuted for perjury.
