Parth Shah, PharmD, PhD, of the Fred Hutchinson Cancer Research Center, led a discussion on the uptake challenges of the human papilloma virus (HPV) vaccine at the American Society of Clinical Oncology’s Annual Meeting by first explaining the known percentages of attributable cancers to the virus in the United States: cervical cancer 91%, vagina cancer 75%, and vulva cancer 69%, among others. Although multiple cancers are attributable to the virus, explained Shah, of the population ages 13-17 in the United States that should be vaccinated, both boys and girls, only 49% actually receive the vaccine.
