Have researchers discovered some reported cases of children who have not received vaccinations developing autism?

No link connecting: Not only are there cases of children developing autism who have not received vaccines, there is no shred of evidence to support vaccines as causing autism. The article that purported to show this has been retracted. Millions of dollars have been spent looking for this link and not a single link has been found. Don't listen to jenny mccarthy, follow the science.

Yes - many: A few years ago it was thought that some vaccinations may have lead to autism. We now know that this research was faked and there is in fact no connection between autism and vaccinations. There are many reported cased world wide of children developing autism who have never received any vaccinations.
