Objective:

To evaluate the association between 9-valent HPV vaccination and the incidence of specific HPV-related cancers (head and neck, esophageal, penile, and anal) in males aged 9 to 26 years.

Key Findings:
  • Vaccinated males had a lower incidence of HPV-related cancers compared to unvaccinated males, with a hazard ratio of 0.54 (95% CI, 0.37–0.81), indicating a 46% lower risk among vaccinated individuals.
  • The difference in cancer incidence was primarily driven by head and neck cancers.
Interpretation:

The study suggests a significant association between HPV vaccination and reduced cancer risk in males, supporting the need for sex-neutral vaccination programs.

Limitations:
  • Cancer diagnoses were based on administrative coding without histologic confirmation, which may have led to misclassification, potentially affecting the reliability of the findings.
  • Vaccination records outside participating health care centers were not captured, meaning some patients categorized as unvaccinated may have received the vaccine elsewhere, which could skew results.
  • Key risk factors such as high-risk sexual behavior were not fully accounted for, which may limit the understanding of the association.
Conclusion:

The findings support the expansion of HPV vaccination to young males, emphasizing the importance of sex-neutral vaccination programs to improve public health outcomes.
