“None of those vaccines alter your DNA. They do not have any of the genetic elements or protein accessories necessary for them to insert into your DNA.”

One of my first steps when dealing with an anti-science nut is to look up the qualifications of those they are promoting as "experts." For example:

"Sherri Tenpenny is an American osteopathic physician and anti-vaccination activist who supports the disproved hypothesis that vaccines cause autism.[1] She is the author of four books opposing vaccination, and her 2015 lecture tour of Australia was cancelled due to a public outcry over her views on vaccination, which go against the established scientific consensus.[1]"

The references in the Wikipedia article are pretty clear: Tenpenny is a fruitcake who promotes anti-science for profit.
