The 2023 Korean sexually transmitted infections guidelines by the Korean Association of Urogenital Tract Infection and Inflammation: Human papillomavirus vaccination

The Korean Association of Urogenital Tract Infection and Inflammation (KAUTII) and the Korea Disease Control and Prevention Agency updated the guidelines for human papillomavirus (HPV) vaccine against sexually transmitted HPV infections in Korea to respond to changing epidemiologic trends, evolving scientific evidence, and advances in laboratory diagnostics and research. Main purpose and recommendation of vaccination against HPV are as follows: (1) the purpose of HPV vaccine is to reduce the risk of genital warts and HPV-related cancers including cervical and vulvar cancer, head and neck cancer, anal cancer, and penile cancer; (2) in Korea, bivalent (16, 18) vaccines, quadrivalent vaccines (6, 11, 16, 18), and 9-valent vaccines (6, 11, 16, 18, 31, 33, 45, 52, 58) are used depending on the type of HPV; (3) bivalent and quadrivalent vaccines are national immunizations targeting girls aged 11-12 years and low-income young females aged 18-26 years (age and range of inoculation: routinely administered at 11 or 12 years of age, 2 doses at 0 and 6 months for 12-14 years of age; for females aged 15-26 years, 3 doses depending on the type of vaccine; vaccination can be given to those aged up to 45 years through consultation with a clinician); (4) in the case of administering 2 doses, at least 5 months apart; in the case of administering 3 doses, it is recommended to keep 4 weeks between the 1st and 2nd doses, 12 weeks between the 2nd and 3rd doses, and 5 months between the 1st and 3rd doses; (5) immunocompromised patients such as those with HIV, malignant neoplasms, and autoimmune diseases, and those undergoing transplantation or immunosuppressive therapy should receive 3 doses. HPV vaccine is not recommended during pregnancy.

Public health impact and cost-effectiveness of implementing gender-neutral immunization with the nonavalent human papillomavirus vaccine in South Korea

This study assessed the impact and cost-effectiveness of gender-neutral immunization with the nonavalent human papillomavirus (HPV) vaccine in South Korea. An established dynamic transmission model of HPV epidemiology was adapted to the South Korean population. Vaccinating both girls and boys with the nonavalent HPV vaccine was compared to the currently administered program of vaccinating girls only with the quadrivalent vaccine. Compared to vaccination of girls only with the quadrivalent HPV vaccine, gender-neutral vaccination with the nonavalent HPV vaccine was projected to prevent 1,282,415 cases of cervical intraepithelial neoplasia grade 1 (CIN1), 918,384 cases of CIN2/3, 36,248 cases of cervical cancer, and 9,313 cervical cancer deaths in females over 100 years. Gender-neutral vaccination was projected to reduce HPV-related vaginal, vulvar, anal, and head & neck cancers in females by 4.8-8.2%, in addition to reductions of 14.6% and 15.8% in genital warts and recurrent respiratory papillomatosis, respectively. In males, gender-neutral vaccination was projected to prevent 666,182 cases of genital warts, 7,422 cases of RRP, 995 cases of anal cancer, 2,441 cases of head & neck cancer, and 122 cases of penile cancer. The incremental cost-effectiveness ratio (ICER) was ₩38.9 million per quality-adjusted life year (QALY), which is below the accepted cost-effectiveness threshold in South Korea. These findings suggest that gender-neutral vaccination with the nonavalent HPV vaccine would reduce the public health burden of HPV disease in both females and males in South Korea and would be cost-effective under base case assumptions about vaccine price and coverage of boys.
