Ian Hector Frazer (born 6 January 1953) is a Scottish-born Australian immunologist, the founding CEO and Director of Research of the Translational Research Institute (Australia).
Frazer and Jian Zhou developed and patented the basic technology behind the HPV vaccine against cervical cancer at the University of Queensland.
The vaccine, now marketed as Gardasil and Cervarix, was the second cancer preventing vaccine, and the first vaccine designed to prevent a cancer.
Researchers at the National Cancer Institute, Georgetown University, and University of Rochester also contributed to the further development of the cervical cancer vaccine in parallel.
