Study: Vaccines Don't Lead to Autism


A new study published in the Journal of Pediatrics Friday reveals no association between autism and the number of vaccines a child gets in one day or during the first two years of the current vaccine schedule.

Researchers, led by Dr. Frank DeStefano, director of the Immunization Safety Office at the Centers for Disease Control and Prevention, sought once again to reassure expectant parents wary of the recommended vaccines their newborns are supposed to get in the first years of life.

The latest findings add to an already-significant body of existing research that discredits the now-retracted 1998 study in the British medical journal BMJ that suggested a link between autism spectrum disorder (ASD) and childhood vaccinations. The study has been discredited as an “elaborate fraud,” but not before some serious damage was done to public perceptions of vaccinations. 

DeStefano and his team collected data on 256 children with ASD and 752 children who did not have autism and monitored how many vaccines and antigens they were exposed to. Both children with ASD and those without had the same amount of antigen, suggestion no correlation between antigenic exposure and the development of autism.

The study’s takeaway: "I would tell an expectant mom that one of the more important things you can do to protect an infant's health is get them vaccinated on time according to the recommended schedule," DeStefano told CNN.
