Abstract

Human papillomavirus (HPV) infection is the world’s most common sexually transmitted infection. It is a prerequisite for cervical cancer, the second most common cause of death in cancer among women worldwide, and is also believed to cause other anogenital and head and neck cancers. Vaccines that protect against the most common cancer-causing HPV types have recently become available, and different countries have taken different approaches to implementing vaccination. This paper examines the ethics of alternative HPV vaccination strategies. It devotes particular attention to the major arguments for and against one strategy: voluntary, publicly funded vaccination for all adolescent boys and girls. This approach seems attractive because it would protect more people against cervical cancer and other HPV-related cancers than less inclusive alternatives, without the sacrifice of autonomy that a comparably broad compulsory programme would require. Also, the herd immunity that it would likely generate would protect those who remain unvaccinated, a major advantage from a justice perspective. However, there is a possibility that a HPV vaccination programme targeting all adolescents of both sexes is not considered sufficiently cost-effective. Also, it might pose more difficulties for achieving informed consent than comparable vaccination programmes against other diseases. Ultimately, society’s choice of HPV vaccination strategy requires careful consideration not only of the values at stake but also of available and emerging scientific evidence.
