Human papillomavirus vaccination coverage among adolescent boys and girls in the United States: A birth year cohort analysis of the National Immunization Survey-Teen, 2016–2022.

Abstract

Objective

To evaluate human papillomavirus (HPV) vaccination coverage among adolescents in the U.S. using birth cohort analysis.

Methods

We conducted a birth cohort analysis among adolescents born during 1999–2009 using National Immunization Survey-Teen (NIS-Teen), a random-digit dialed household telephone survey that also includes vaccination data from providers. We analyzed 131,553 records from 2016 to 2022 NIS-Teen data to determine: trends in coverage with ≥1 HPV vaccine dose before age 13 years and cumulative coverage from age 13–17 years; sociodemographic factors associated with HPV vaccination before age 13 years; missed HPV vaccination opportunities and the potential achievable coverage if opportunities were not missed; and trends in completion of HPV vaccination series. Regression analysis and Kaplan-Meier method provided the average percentage increase in coverage, and cumulative coverage from age 13–17 years stratified by birth cohorts, respectively.

Results

HPV vaccination initiation before age 13 years increased from 27.0 % among adolescents born in 1999 to 69.8 % among those born in 2009. Overall, cumulative percent with ≥1 HPV vaccine dose increased from 51.3 % before age 13 years to 74.9 % through age 17 years. Having a preventive visit at ages 11–12 years and being insured were associated with higher ≥1 HPV vaccine dose coverage. Among the 38,568 (29.3 %) adolescents unvaccinated for HPV, 31,513 (82.5 %) missed ≥1 HPV vaccination opportunity. The potential achievable coverage if opportunities were not missed was 94.8 %. Completion of HPV vaccination series before age 13 years increased from 10.3 % among adolescents born in 1999 to 42.2 % among those born in 2009.

Conclusions

Coverage with ≥1 HPV vaccine dose increased by birth cohort among adolescents born 1999–2009 but remained suboptimal, especially among uninsured adolescents. Missed opportunities may be reduced by effective HPV vaccination implementation and uptake strategies and by administering all recommended vaccines during the same visit.
