    Thanks for the great (as always) episode this week. I feel like one important point was omitted during the discussion of the rational of vaccinating men against HPV. In addition to serving as a vector for cervical cancer in women, men are susceptible to anal cancer linked to HPV. Rates of anal cancer are particularly high in at-risk populations like men who have sex with men (JAMA. 1982;247(14):1988.) I don’t know if the cost-benefit analysis has been performed for vaccinating to prevent anal cancer, as it was with cervical cancer. But it is an important point that parents and individual patients should consider when thinking about getting vaccinated against HPV.

    Great show though. The HPV vaccine is such an important accomplishment in modern medicine, and I appreciate you highlighting it.

    Thanks,
