Stephanie Messenger

Stephanie Frances Bailey (born 26 July 1970), more commonly known by the Australian Registered Business Name Stephanie Messenger, is an anti-vaccination activist, lecturer and author from Brisbane, Australia who believes her son was killed by vaccination. She writes children's books focusing on health and social issues, her most noteworthy being Melanie's Marvelous Measles which was published in 2012 but received considerable media attention after the Disneyland measles outbreak in 2014. Messenger organised a 2015 lecture tour of Australia for fellow anti-vaccinationist Sherri Tenpenny. The tour was cancelled due to public outcry over the anti-vaccination stance of the tour.
