On a 1989 sabbatical he met virologistJian Zhou, and the two considered the problem of developing a vaccine for HPV – a virus that cannot be cultured without living tissue.[12] Frazer convinced Zhou to join him, and in 1990 they began to use molecular biology to synthesize particles in vitro that could mimic the virus. In March 1991 Zhou's wife and fellow researcher, Xiao-Yi Sun,[8] assembled by Zhou's instructions[13] two proteins into a virus-like particle (VLP),[14] resembling the HPV shell, from which HPV vaccine would ultimately be made.[5] The vaccine completely protects unexposed women against four HPV strains responsible for 70% of cervical cancers,[15][16] which kill about 250,000 women annually.[17][18] Frazer and Zhou filed a provisional patent in June 1991 and began work on developing the vaccine within UQ. To finance clinical trials, Australian medical company CSL, and later Merck, were sold partial patents.[19] (CSL has the exclusive license to sell Gardasil in New Zealand and Australia, Merck the license elsewhere.)[20]GlaxoSmithKline independently used the same VLP-approach to develop Cervarix, under a later US patent, licensing Frazer's intellectual property in 2005.[21]
Later in 1991 the research was presented at a US scientific meeting, and Frazer became Director of the Centre for Immunology and Cancer Research at the University of Queensland (later renamed The Diamantina Institute for Cancer, Immunology and Metabolic Medicine, where he held a personal chair as director). After three years in design, Gardasil went into testing, and Frazer became a professor in the university's Department of Medicine. In 1998 Frazer completed the first human trials for Gardasil, and became an Australian citizen.[4][14]
Pioneer Patent for VLPs and the HPV vaccine
US. 7,476,389, titled "Papilloma Virus Vaccines", was granted to co-inventors Ian Frazer and Jian Zhou (posthumously) on 13 January 2009. Its U.S. application was filed on 19 January 1994, but claimed priority under a 20 July 1992 PCT filing to the date of an initial [AU] Australian patent application filed on 19 July 1991.
Celebrity
In 2006 results from the four-year Phase III trials led to Australian and US regulatory approval.[14] Frazer's studies showed 100% efficacious protective immunity in HPV naïve women, but could not directly test protective immunity (against HPV exposure) in adolescent girls. As a surrogate test, antibody titer levels in vaccinated 9 to 15-year-old girls was shown high enough to give them the same level of immunity as vaccinated women.[22] It has been suggested that one way to bring cheaper equivalent vaccines to market is to mandate a similar induced immune response.[23]
In the 2007 resolution of their US patent lawsuit, Frazer's and Jian Zhou's heirs (Zhou, who died in 1999, was survived by his widow Xiao-Yi Sun and a son Andreas) world-wide rights to the fundamental VLP science, and Frazer's and Zhou's priority to invention of that fundamental VLP science, were both established.[6][21]
After 2009 reports of adverse Gardasil reactions, Frazer said "Apart from a very, very rare instance where you get an allergic reaction from the vaccine, which is about one in a million, there is nothing else that can be directly attributable to the vaccine."[27] Ian Frazer is one of the "most trusted" Australians, and some critics have accused Gardasil's advocates of exploiting patriotism[28] to promote its rapid Australian release.[29] (Australia's government had the world's most generous coverage for the drug, though it is the nation with the lowest cervical cancer mortality.)[20]
On 11 June 2012, Frazer was named a Companion of the Order of Australia (AC) for "eminent service to medical research, particularly through leadership roles in the discovery of the Human Papilloma Virus vaccine and its role in preventing cervical cancer, to higher education and as a supporter of charitable organisations."[40]
Current work
Herpes
In February 2014, it was announced that Frazer's new vaccine against genital herpes has passed human safety trials in a trial of 20 Australians. The vaccine is designed to prevent new infections.[41]
Frazer is the inaugural holder of the Queensland Government Smart State premier's fellowship, worth $2.5 million over 5 years. He has held continuous research funding from the National Health and Medical Research Council (NHMRC) since 1985, mostly relating to papilloma viruses or tumor immunology. He is currently a joint Chief Investigator on an NHMRC program grant and a NHMRC/Wellcome program grant, together worth more than $2 million a year.

Estimates of the contemporary global mortality rate have remained in the 190,000 to 300,000 range from 2000 to 2010. The 2007 WHO progress report says that preventable cervical cancer "was responsible in 2005 for up to 500,000 new cases, and up to 257,000 deaths, more than 90% in low- and middle-income countries", but, "According to WHO’s projections, deaths from cervical cancer will rise to 320,000 in 2015 and to 435,000 in 2030" (p.4). These projections may be little effected by vaccination programs (anyway unlikely on cost grounds) because "A reduction in cancer incidence and mortality might not be measurable before 10 to 30 years after the vaccine is introduced." (p.5). Other estimates of the problem's scale are broadly in agreement:
Kennedy, F. (25 January 2006). "UQ Australian of the Year Will Continue Fight for Women's Health". UQ News. Professor Frazer said Australia and other developed nations had effective Pap smear programs to reduce the incidence of cervical cancer. 'Despite this, cervical cancer continues to be a shocking disease for women in the developed world. Women living in poverty in the developing world, where Pap smears are not widely available, account for most of the 250,000 deaths from cervical cancer each year. So this vaccine has the potential to do most good in the developing world, where it could help lift women out of poverty by relieving the burden of disease
