"There is no science to back up the statement as far as what the CDC's provided to say that vaccines, plural, do not cause autism," Bigtree told The Epoch Times. "This is a false statement."

"We will bring a case against the CDC to remove that from the website because it is actually inaccurate," he added.

Bigtree says that the CDC has not been able to provide his organization studies that concretely show vaccines given to infants in the first six months of life do not cause autism, a neurological and developmental disorder that may be diagnosed as early as six to 12 months.

"If vaccines contribute to the issue, certainly we can isolate it inside of the vaccines given in the first six months of life because autism is appearing at six months," Bigtree said.
