Immunologist Professor Ian Frazer has been named the winner of the prestigious AMA Gold Medal.
Prof Fraser, who developed human papillomavirus cervical cancer vaccines, was honoured at the AMA National Conference dinner last night.
"The Gold Medal is the highest award the AMA can bestow," the Association's President, Dr Rosanna Capolingua said.
"Through the development of vaccines Ian has helped protect the lives of countless women and he is truly deserving of this honour."
Prof Fraser was unable to be present at the ceremony last night.
He won the 2005 CSIRO Eureka Prize for Leadership in Science, was named Australian of the Year for 2006, won the Howard Florey Medal for Medical Research in 2007 and was recently made a fellow of the Australian Academy of Science.
