The only study I heard Anti-Vaxxers ask for is a RETROSPECTIVE Vaxxed vs UnVaxxed Study.
Congress requested from the CDC a Vaxxed vs Unvaxxed Study, but the CDC refuses.
There are no ethical issues with a RETROSPECTIVE study, so why does the CDC refuse?
Because it would reveal that the CDC LIED – that vaccines DO cause Autism and many other sicknesses.
There already have been several Vaxxed vs UnVaxxed studies and they show that Unvaccinated Children
are Far Healthier with much less Autism, Allergies, Asthma, Ear Infections, ADHD etc.
