Gardasil’s 20-year milestone and worldwide impact
The human papillomavirus (HPV) vaccine Gardasil, co-developed at the University of Queensland by Professor Ian Frazer and the late Dr Jian Zhou, marked its 20th anniversary in 2026. More than 800 million doses have been administered globally, and the vaccine is now part of national immunisation programmes in 165 countries. The Gavi Vaccine Alliance estimates that a three-year programme beginning in 2023 could prevent 1.4 million future deaths in low- and middle-income nations. The World Health Organization’s 2020 cervical-cancer-elimination strategy projects 62 million lives saved by 2120, with Gardasil as a central tool.
Australia’s trajectory toward eliminating cervical cancer
Australia was the first nation to fully fund an HPV immunisation programme. Girls and young women have received Gardasil free of charge since 2007, and boys and young men were added in 2013. The programme was scheduled for its inaugural teenage vaccinations on August 28, 2006. Griffith University infectious-diseases professor Nigel McMillan has said Australia could see only sporadic cases within the next decade, describing cervical cancer as “a disease of the past.” European health agencies are reporting similarly strong effectiveness, reinforcing the vaccine’s role in a global elimination strategy.
Declining domestic coverage raises concern
Australian Immunisation Register data show that HPV-vaccine coverage for girls by age 15 fell from 86.6 % in 2020 to 78.7 % in 2025, while coverage for boys dropped from 84.9 % to 75.6 % over the same period. University of Melbourne professor Julia Brotherton characterised the slide below the 80 % threshold as “really concerning,” noting that hesitancy and misinformation are increasing despite the vaccine’s long-standing safety record.
Official perspectives on safety and uptake
Professor McMillan reiterated his confidence in the vaccine’s safety, stating he had “no hesitation” to vaccinate his own daughters after reviewing trial data.
