As for the “Danish Study”, two seconds on Google found an article on the website “Science Based Medicine”, search for the title “The curious case of Poul Thorsen, fraud and embezzlement, and the Danish vaccine-autism studies”.
Basically, Thorsen is a fraud. But he only worked on two studies and wasn’t even the primary researcher on either. The data from the studies is still valid and so is the data on dozens of other studies that show no link between immunization and autism.
