A groundbreaking study led by the University of Otago, Christchurch, has confirmed the effectiveness of the human papillomavirus (HPV) vaccination program in preventing cervical cancer. The findings, published in the Journal of the Royal Society of New Zealand, highlight the significant impact of the vaccination program introduced in 2008.
Vaccination Program Success
Lead author Associate Professor Peter Sykes, from the Department of Obstetrics and Gynaecology, emphasized the importance of HPV vaccination, stating that it “can and will prevent cervical cancer in Aotearoa New Zealand.” He urged widespread adoption of the vaccine, citing its additional benefits in preventing other HPV-related diseases, including cancers of the mouth and throat.
Study Findings
Researchers analyzed data from the National Cervical Screening Program, matching it with the national vaccination register to examine the incidence of cervical abnormalities. The study found a significant decrease in cervical cancer cases among vaccinated individuals, with a lower likelihood of developing precancerous changes requiring medical intervention.
The findings suggest that individuals vaccinated at a younger age reap the most benefits, reinforcing the need to target those under 16 in vaccination efforts. Furthermore, the research highlighted the program’s role in promoting health equity, as vaccination access was found to be equitable among Māori, Pacific, and European populations.
Call for Increased Vaccination Rates
Despite the program’s success, Associate Professor Sykes noted that vaccination rates remain low, particularly among Māori, and declined further during the COVID-19 pandemic. He stressed the need to improve vaccination rates to meet the World Health Organization’s (WHO) goal of vaccinating 90 percent of young people.
“If the promise of cervical cancer elimination for all people in Aotearoa New Zealand is to be achieved, it is essential that we equitably improve vaccination rates,” Sykes said. “We need to invest further to meet the goal of eradicating cervical cancer as a public health problem for all.”
Continued Screening Still Necessary
While the study affirms the efficacy of the HPV vaccine, researchers caution that it does not prevent all forms of cancer. They strongly encourage individuals to adhere to cervical screening guidelines to ensure early detection and treatment of potential abnormalities.
