You can read it here:

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.

Just to be clear: the vaccine-autism link is a hoax.

The doctor who came up with it was in cahoots with the lawyers, and he had a patent on a junk science alternative.

He is now in the process of having his license to practice medicine stripped.
