Pros, cons, and ethics of HPV vaccine in teens-Why such controversy?

introductionHuman papillomavirus (HPV) infection remains one of the most commonly sexually transmitted infections in both females and males. HPV viruses are associated with several manifestations including genital warts, but more importantly for urology practitioners, cervical and penile carcinomas and recurrent genital condylomata in both sexes. The incidence of HPV-related carcinomas has increased in cervical, oropharyngeal, vulvar, penile, and anal cancers. Effective vaccines have been available for almost a decade, but widespread adoption of vaccine administration has been problematic for multiple reasons. Many countries (over 100) have adopted vaccine programs for females and an increasing number of countries are extending the indications to include males between the ages of 9-26. There still seems to be controversy surrounding these universal vaccination programs as well as some ethical and practical concerns regarding the administration of a vaccine for diseases that are associated with sexual contact in both sexes, especially during the early adolescent years.

objectiveThe objective was to provide a review of the available literature so pediatric and adult urologists may be more aware of the issues related to HPV vaccination in order to more effectively counsel patients and parents regarding the risks, benefits, and public health issues regarding HPV vaccination. This topic is especially relevant to pediatric urologists who see patients in the target age group for the HPV vaccine. There has been an explosion of literature regarding HPV vaccination programs and the relative difficulty in adopting the vaccine series with a completion rate of under 50% of patients in the recommended age ranges for vaccination.

methodsArticles were obtained from an extensive Medline literature search (1998-present) to evaluate the current HPV vaccination regimens for teenagers with special emphasis on the urologically focused disease burden.

resultsThe adoption of universal HPV vaccination has been difficult, but appears to be increasing over time as public education improves and governmentally- mandated vaccine programs increase. Despite the ethical concerns raised, the benefits of vaccination with regard to cancer prevention outweigh the risks and potential side effects related to the quadrivalent vaccine administration. Clearly, more follow-up over time is required to document these improvements in public health. Urologists need to remain aware of the prevention strategies for HPV infection and should help with counseling parents and patients in the appropriate age groups for HPV vaccination. Urology providers need to help engage and educate the parents and teenage patients to help promote broader adoption of the HPV vaccine regimen.
