Allowing the audience a look into her personal life, Shanahan explained her daughter was healthy and seemed fine until after she received a vaccine when she was seven-months old.

"I had an enormous amount of grief, but then set in the confusion because I was not allowed to consider the fact that the shot caused anything," she said.

After realizing the jab could have been responsible for her daughter's diagnosis, Shanahan said she felt very "alone" because there weren't many people in her life she could talk to about her newfound skepticism.

She explained, "This notion that perhaps the shot caused an adverse reaction, this is a no-go for progressives. You cannot talk about these things amongst these communities."

RFK Jr. recently exposed the autism-vaccine connection during an interview with John Stossel, pointing out that some of the CDC's own data proved the connection between vaccines and autism before the agency started paying "biostitutes" to release studies creating the illusion that shots don't cause the neurodevelopmental disorder.
