You are taking Mrs. Gerberding's words out of context. Children with a specific mitochondrial disorder may develop a wide range of issues from a vaccine. This does include autism, but it is very limited and the benefits still out way the risks. If 10% of the time, vaccines caused autism, we would see 400,000 new cases every year. If it was 5%, it would be 200,000 new cases per year. The US currently has a total of about 550,000 cases.

Just Polio and Measles effected approximately 25% of the population before the vaccines. That would mean, that even just these two illnesses would effect around 1,000,000 kids per year. Which is more risky?

My ignorance comes from actually knowing the facts of the case, and trying to tell someone to keep quite rather than disputing their points, shows how hollow your argument is.
