On its website, VacTruth, which was founded in 2009 by Navy veteran Jeffry John Aufderheide, states that its mission “is to help [parents] find information on vaccine ingredients and reactions” to free them from “fear.”

“For the readers who have asked this question,” VacTruth wrote on its Facebook page. “Do you think vaccinating a child with vaccines, that are made up of endocrine disrupting chemicals, can affect the outcome of a person's sexuality? Homosexuality is found in nature in other species and has occurred in populations long before the advent of vaccines. Some believe vaccines affect sexuality and some don’t. It is known that vaccines do disrupt hormonal function and can cause fertility and thyroid problems, so this is a legitimate question some people want to learn more about.”

According to thespudd.com, a site that works to expose “pseudoscience and quackery,” the comments of outraged readers were deleted and they were banned from VacTruth's page.

“This is a familiar trick employed by anti-vaccine advocates – create an echo chamber on their websites and Facebook pages to make it appear as though everyone agrees with what they are saying,” the site wrote.
