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.

青少年人乳头瘤病毒疫苗接种趋势：2015 年至 2020 年。

目的 评估近期人乳头瘤病毒 (HPV) 疫苗接种的趋势以及与青少年接种疫苗相关的因素。方法 2015 年至 2020 年全国免疫调查 - 青少年数据用于评估疫苗接种趋势。进行多变量逻辑回归分析以评估与疫苗接种相关的因素。结果 总体而言，青少年 HPV 疫苗接种覆盖率（≥1 剂）从 2015 年的 56.1% 显着增加至 2020 年的 75.4%。男性（每年 4.7 个百分点）的覆盖率增幅大于女性（每年 2.7 个百分点）和覆盖率2015 年至 2020 年，男性和女性之间的差异有所减少。 2020 年 13 至 17 岁青少年的覆盖率为 75.4%；男性为 73.7%，女性为 76.8% (P < .05)；80. 有提供者推荐者为 7%，无提供者推荐者为 51.7% (P < .05)；80.3% 的儿童在 11 至 12 岁时就诊，64.8% 的儿童没有 (P < .05)。多变量逻辑回归结果显示，与较高的疫苗接种可能性独立相关的主要特征包括：提供者建议、年龄 16 至 17 岁、非西班牙裔黑人、西班牙裔或美洲印第安人或阿拉斯加原住民、医疗补助保险、≥2 个提供者联系过去 12 个月，11 至 12 岁的健康儿童就诊，并有 1 或 2 名疫苗提供者 (P < .05)。结论 总体而言，2015 年至 2020 年期间，青少年 HPV 疫苗接种覆盖率有所增加。男性的覆盖率增长速度快于女性，并且在此期间性别差异缩小。
