Like Jason, I was not happy to learn that Barack Obama, like John McCain, had given credence to the supposed link between autism and vaccines. Well, it turns out that opinion is unanimous among the presidential candidates. Here is how Hillary Clinton's campaign answered a questionnaire from the group A_Champ:

Q: Do you think vaccines should be investigated as a possible cause of autism? 

A: I am committed to make investments to find the causes of autism, including possible environmental causes like vaccines. I have long been a supporter of increased research to determine the links between environmental factors and diseases, and I believe we should increase the NIH’s ability to engage in this type of research. My administration will be committed to improving research to support fact-based solutions, and I will ensure that the NIH has the staff and funding to fully explore all possible causes of autism.


Q: Would you support a large-scale federal study of the differences in health outcomes between vaccinated and unvaccinated groups? 

A: Yes. We don’t know what, if any, kind of link there is between vaccines and autism - but we should find out. The lack of research on treatments, interventions, and services for children and adults with autism is a major impediment to the development of delivery of quality care. We need evidence-based research on what works and what doesn’t in order to provide the most effective services for people with autism. In addition to a large-scale federal study, I will create a task force that would include significant representation from the autism community and would be charged with identifying gaps in evidence-based biomedical research, behavioral treatments, and services for children and adults with autism. The task force would present these findings to Congress and the Executive Branch and would make recommendations on how to make evidence-based treatments, interventions, and services available at the state and local levels. Once the task force has completed its work, I will provide funding to establish state-based demonstration grants to provide these evidence-based autism treatments, interventions, and services.
