Trends in adolescent human papillomavirus vaccination and parental hesitancy in the United States.

BACKGROUND: Human papillomavirus (HPV) vaccination coverage remains suboptimal in the U.S., underscoring the importance of monitoring trends in vaccine hesitancy.

METHODS: 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.

RESULTS: 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).

CONCLUSIONS: 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.
