Trends in adolescent human papillomavirus vaccination and parental hesitancy in the United States
Menée à partir des données d'une enquête réalisée aux Etats-Unis sur la période 2011-2020, cette étude analyse l'évolution du taux de vaccination contre le papillomavirus humain (HPV) chez les adolescents âgés de 13 à 17 ans et identifie les facteurs de défiance des parents vis-à-vis du vaccin anti-HPV
Human papillomavirus (HPV) vaccination coverage remains suboptimal in the U.S., underscoring the importance of monitoring trends in vaccine hesitancy.Cross-sectional data from the 2011-2020 National Immunization Survey-Teen were used to assess trends in provider-verified HPV vaccination initiation (≥1 dose) among 13-17-year-olds, parental intent to initiate vaccination, and primary reasons for parental hesitancy.Among all sex and race and ethnicity groups, prevalence of HPV vaccination initiation increased over time, but parental intent to vaccinate against HPV for unvaccinated teens remained consistently low (≤45%). Among hesitant parents, ‘safety concerns’ increased in nearly all demographic groups with the greatest increases observed for non-Hispanic White female and male teens; no change was observed for non-Hispanic Black female teens. In 2019-2020, parents of unvaccinated non-Hispanic White teens were least likely to intend on vaccinating against HPV, and the most common hesitancy reason varied by sex and race and ethnicity (e.g., ‘safety concerns’ for White teens and ‘not necessary’ for Black female teens).Although HPV vaccination initiation increased over time, a substantial fraction of parents remain hesitant and trends in the reason for hesitancy varied by sex and race and ethnicity. Health campaigns and clinicians should address vaccine safety and necessity.Adolescent vaccination against human papillomavirus (HPV) is a critical tool for cancer prevention. We analyzed trends in HPV vaccination initiation among adolescents aged 13-17 years and trends in parental hesitancy to initiate HPV vaccination for their teen using data from a national survey in the U.S. Between 2011-2012 and 2019-2020, coverage of adolescent HPV vaccination initiation increased over time for female teens (53.4% to 75.2%) and for male teens (14.5% to 71.5%). However, the majority of parents/guardians of unvaccinated teens did not intend to vaccinate their teen against HPV (i.e., vaccine hesitant), and this was consistent over time in all sex and race and ethnicity groups. Among hesitant parents, the proportion reporting safety concerns as their main reason for being hesitant increased over time in nearly all demographic groups, with the greatest increases in this reasoning observed for white teens. In 2019-2020, parents of unvaccinated white teens were most likely to be vaccine hesitant. The most common reason for being vaccine hesitant also differed by sex and race and ethnicity. Although HPV vaccination has been shown to be safe and effective, HPV vaccination coverage remains suboptimal, and a substantial fraction of parents/guardians continue to be hesitant to adolescent HPV vaccination.
