Sherri Tenpenny


Sherri Tenpenny is an American osteopathic physician and anti-vaccination activist who supports the discredited hypothesis that vaccines cause autism. 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. She has no advanced clinical or research specialization in immunology, vaccinology, or public health, nor has she ever published peer-reviewed research in any area related to vaccines or immunology.

Education and career

Tenpenny graduated with a Bachelor of Arts from the University of Toledo in 1980, and subsequently received a Doctor of Osteopathic Medicine degree from the Kirksville College of Osteopathic Medicine in Missouri in 1984.
From 1986 to 1998, Tenpenny was the director of the emergency department at Blanchard Valley Hospital in Findlay, Ohio. She opened an osteopathic practice in 1994, and went on to establish two more such practices, in 1996 and 2011.
Tenpenny had scheduled a speaking tour in Australia to occur starting in February 2015, but after objections were raised to her anti-vaccination views, all the venues at which she was scheduled to speak cancelled the talks in January, and the tour was called off.
