Bazelon: “One of the reasons people cite for opting out is the fear of autism. Is there any evidence that is a legitimate concern?”
Spiesel: There are actually two concerns. One is thimerosal, and the other is measles, mumps and rubella vaccine. The MMR vaccine concerns were based on what turned out to be very bad research. And there’s a lot of evidence that neither the MMR vaccine, nor thimerosal, nor the number of vaccines a children receives at one time has any role to play in autism. In fact there are some good immunological reasons that most people don’t know about that bunching some vaccines together increases the response.”
