In this episode of After Hours Clinic, Andrew Lane and Dr. David Janarious examine new research published in JAMA on the HPV vaccine and its association with reduced cancer risk in males. The discussion breaks down how the human papillomavirus contributes to cervical, head and neck, esophageal, anal, and penile cancers, and why vaccination recommendations expanded from girls to boys over the past two decades. Andrew reviews the strengths and limitations of the large population study, including the reported reduction in HPV-related cancers among vaccinated males. The conversation also addresses vaccine safety data, public distrust of medical institutions, risk versus benefit analysis, and whether HPV vaccination may still offer value later in adulthood.
