OBJECTIVE To assess trends in recent human papillomavirus (HPV) vaccination initiation and factors associated with vaccination among adolescents. METHODS The 2015 to 2020 National Immunization Survey-Teen data were used to assess vaccination trends. Multivariable logistic regression analysis were conducted to assess factors associated with vaccination. RESULTS Overall, HPV vaccination coverage (≥1 dose) among adolescents significantly increased from 56.1% in 2015 to 75.4% in 2020. There were larger increases in coverage among males (4.7 percentage points annually) than females (2.7 percentage points annually) and coverage differences between males and females decreased in 2015 through 2020. Coverage in 2020 was 75.4% for adolescents aged 13 to 17 years; 73.7% for males and 76.8% for females (P < .05); 80.7% for those with a provider recommendation and 51.7% for those without (P < .05); and 80.3% for those with a well child visit at age 11 to 12 years, and 64.8% for those without (P < .05). Multivariable logistic regression results showed that main characteristics independently associated with a higher likelihood of vaccination included: a provider recommendation, age 16 to 17 years, non-Hispanic Black, Hispanic, or American Indian or Alaskan Native, Medicaid insurance, ≥2 provider contacts in the past 12 months, a well-child visit at age 11 to 12 years and having 1 or 2 vaccine providers (P < .05). CONCLUSIONS Overall, HPV vaccination coverage among adolescents increased during 2015 to 2020. Coverage increased faster among males than females and differences by sex narrowed during this time. Receiving a provider recommendation vaccination was important to increase vaccination coverage.
