Comparison of HPV prevalence between HPV-vaccinated and non-vaccinated young adult women (20-26 years)

Although the HPV vaccine provides protection against genital warts and HPV-associated anogenital cancers among young girls, there is some concern about its effectiveness when administered to young adult women due to the risk of prior HPV infections before vaccination and potentially reduced immunogenicity when administered at older ages. This study used 2 cycles of the National Health and Nutrition Examination Survey (NHANES) data to evaluate the effectiveness of the HPV vaccine among women 20-26 years of age.
