HPV Vaccination Decline Threatens Cervical Cancer Progress in Far North Queensland

Far North Queensland is experiencing a decline in school-based human papillomavirus (HPV) vaccination rates, which public health experts state could jeopardize progress against cervical cancer.

New data from the Cairns Public Health Unit indicates that only 56 percent of students received the HPV vaccine last year, a decrease from 61 percent the previous year. This figure is significantly below the national target of 90 percent necessary to eliminate HPV-related cancers.

Statewide Trends and Expert Concerns

While the Cairns data is preliminary, it aligns with statewide figures showing a steady decline in HPV vaccination rates in Queensland since 2019, when first-dose uptake reached 74.5 percent. University of Sydney immunisation researcher Julie Leask expressed concern over the continued decline, noting it is part of a national trend.

Understanding HPV and Its Risks

HPV is the most common sexually transmitted viral infection, affecting approximately 85 percent of sexually active individuals. Certain strains of HPV can lead to cervical cancer, as well as penile cancer, throat cancers, and genital warts.

Australia has been recognized for its HPV prevention efforts, offering free school vaccinations for nearly two decades.

Professor Leask stated that this progress is at risk if vaccination rates continue to fall.

Identified Barriers to Vaccination Uptake

Cairns public health physician Tonia Marquardt identified the primary reason for missed vaccinations as unreturned consent forms from parents and guardians. Other contributing factors include student absences and incorrectly completed forms.

Trinity Bay State High School executive principal Tony Whybird emphasized that low vaccination rates pose a risk to broader community immunity and encouraged families to return consent forms.

Systemic Challenges Beyond Hesitancy

Professor Leask suggested that the problem, particularly in regional areas like Cairns, is driven more by systemic challenges than by vaccine hesitancy. These challenges include increased absenteeism and pressure on school staff, as well as limited resources and fragmented delivery systems for public health teams. She proposed improvements such as greater flexibility in consent methods and proactive parental engagement.

Urgent Public Health Implications

Professor Leask referenced recent measles outbreaks, which followed declining vaccination rates, as an example of potential consequences if HPV coverage continues to decrease. Measles cases in Australia have tripled in recent years, partly attributed to reduced vaccination rates.

She concluded that this is a national, state, and local problem for Cairns.
