Do you have links to case reports of unvaccinated children who develop regressive autism (losing skills overnight)? I have not seen any.
Interesting how you phrased your second sentence. Most of the pro-vaxxers insist that it's never the vaccinations, except when it is -- like Ryan Mojabi, Emily Moller, Hannah Poling, Bailey Banks, whose cases of vaccine-induced regressive autism were all conceded and compensated by the US Department of Health and Human Services.
It's worth noting that Ryan's and Emily's cases were conceded and compensated only a year ago.
The children I know have not been written up in journals. But I know them personally. And they have autism. And they are unvaccinated.
