The CDC claims on its website that "Vaccines Do Not Cause Autism."[1]  Despite this claim, studies have found between 40% and 70% of parents with an autistic child continue to blame vaccines for their child's autism, typically pointing to vaccines given during the first six months of life.[2]

Vaccines given during the first six months of life, according to the CDC's childhood vaccine schedule, include three doses each of DTaP, HepB, Hib, PCV13 and IPV, for a total of fifteen doses in these six months.[3]

In the summer of 2019, ICAN submitted a Freedom of Information Act (FOIA) request to the CDC for "All studies relied upon by CDC to claim that the DTaP vaccine does not cause autism."[4
