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., (Copyright © 2022 by the American Academy of Pediatrics.)

Purpose: Human papillomavirus (HPV) vaccination in the United States has been recommended for girls since 2006 and for boys since 2011. However, settings of receiving HPV vaccination have not been assessed. The purpose of this study is to assess settings of receiving HPV vaccination among adolescents in order to understand what strategies are needed to improve vaccination uptake., Methods: Data from the 2018 National Immunization Survey-Teen (NIS-Teen) were analyzed to assess place of HPV vaccination overall, and by gender, quarter, and other selected variables among adolescents in the United States. The 2016-2018 NIS-Teen data were combined to assess state-specific place of HPV vaccination., Results: Among vaccinated adolescents aged 13-17 years, a doctor's office was the most common place where HPV vaccination was received (79.2%), followed by clinics, health centers, or other medical facilities (13.5%), health department (4.1%), hospital or emergency room (2.3%), schools (.5%), and pharmacies or stores (.4%). Overall, 99.1% of adolescents aged 13-17 years received HPV vaccination at medical settings and only .9% at nonmedical settings. Reported vaccination in nonmedical settings by state ranged from less than .1% in Delaware, Florida, and New Hampshire to 4.1% in North Dakota, with a median of 1.0%., Conclusions: Doctor's offices were the most common medical setting for adolescents to receive HPV vaccination. Less than 1% of adolescents received vaccination at nonmedical settings. Continuing work with medical and nonmedical settings to identify and implement appropriate strategies are needed to improve HPV vaccination coverage among adolescents., (Published by Elsevier Inc.)

The Advisory Committee on Immunization Practices (ACIP) recommends that adolescents aged 11-12 years routinely receive tetanus, diphtheria, and acellular pertussis (Tdap); meningococcal conjugate (MenACWY); and human papillomavirus (HPV) vaccines. Catch-up vaccination is recommended for hepatitis B (HepB); hepatitis A (HepA); measles, mumps, and rubella (MMR); and varicella (VAR) vaccines for adolescents whose childhood vaccinations are not current. Adolescents are also recommended to receive a booster dose of MenACWY vaccine at age 16 years, and shared clinical decision-making is recommended for the serogroup B meningococcal vaccine (MenB) for persons aged 16-23 years (1). To estimate coverage with recommended vaccines, CDC analyzed data from the 2020 National Immunization Survey-Teen (NIS-Teen) for 20,163 adolescents aged 13-17 years.* Coverage with ≥1 dose of HPV vaccine increased from 71.5% in 2019 to 75.1% in 2020. The percentage of adolescents who were up to date † with HPV vaccination (HPV UTD) increased from 54.2% in 2019 to 58.6% in 2020. Coverage with ≥1 dose of Tdap, ≥1 dose (and among adolescents aged 17 years, ≥2 doses) of MenACWY remained similar to coverage in 2019 (90.1%, 89.3%, and 54.4% respectively). Coverage increased for ≥2 doses of HepA among adolescents aged 13-17 years and ≥1 dose of MenB among adolescents aged 17 years. Adolescents living below the federal poverty level § had higher HPV vaccination coverage than adolescents living at or above the poverty level. Adolescents living outside a metropolitan statistical area (MSA) ¶ had lower coverage with ≥1 MenACWY and ≥1 HPV dose, and a lower proportion being HPV UTD than adolescents in MSA principal cities. In 2020, the COVID-19 pandemic disrupted routine immunization services. Results from the 2020 NIS-Teen reflect adolescent vaccination coverage before the COVID-19 pandemic. The 2020 NIS-Teen data could be used to assess the impact of the COVID-19 pandemic on catch-up vaccination but not on routine adolescent vaccination because adolescents included in the survey were aged ≥13 years, past the age when most routine adolescent vaccines are recommended, and most vaccinations occurred before March 2020. Continued efforts to reach adolescents whose routine medical care has been affected by the COVID-19 pandemic are necessary to protect persons and communities from vaccine-preventable diseases and outbreaks., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Three vaccines are recommended by the Advisory Committee on Immunization Practices (ACIP) for routine vaccination of adolescents aged 11-12 years to protect against 1) pertussis; 2) meningococcal disease caused by types A, C, W, and Y; and 3) human papillomavirus (HPV)-associated cancers (1). At age 16 years, a booster dose of quadrivalent meningococcal conjugate vaccine (MenACWY) is recommended. Persons aged 16-23 years can receive serogroup B meningococcal vaccine (MenB), if determined to be appropriate through shared clinical decision-making. CDC analyzed data from the 2019 National Immunization Survey-Teen (NIS-Teen) to estimate vaccination coverage among adolescents aged 13-17 years in the United States.* Coverage with ≥1 dose of HPV vaccine increased from 68.1% in 2018 to 71.5% in 2019, and the percentage of adolescents who were up to date † with the HPV vaccination series (HPV UTD) increased from 51.1% in 2018 to 54.2% in 2019. Both HPV vaccination coverage measures improved among females and males. An increase in adolescent coverage with ≥1 dose of MenACWY (from 86.6% in 2018 to 88.9% in 2019) also was observed. Among adolescents aged 17 years, 53.7% received the booster dose of MenACWY in 2019, not statistically different from 50.8% in 2018; 21.8% received ≥1 dose of MenB, a 4.6 percentage point increase from 17.2% in 2018. Among adolescents living at or above the poverty level, § those living outside a metropolitan statistical area (MSA) ¶ had lower coverage with ≥1 dose of MenACWY and with ≥1 HPV vaccine dose, and a lower percentage were HPV UTD, compared with those living in MSA principal cities. In early 2020, the coronavirus disease 2019 (COVID-19) pandemic changed the way health care providers operate and provide routine and essential services. An examination of Vaccines for Children (VFC) provider ordering data showed that vaccine orders for HPV vaccine; tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap); and MenACWY decreased in mid-March when COVID-19 was declared a national emergency (Supplementary Figure 1, https://stacks.cdc.gov/view/cdc/91795). Ensuring that routine immunization services for adolescents are maintained or reinitiated is essential to continuing progress in protecting persons and communities from vaccine-preventable diseases and outbreaks., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

Introduction: The Delta Regional Authority (DRA) consists of 252 counties and parishes in 8 states in the US Mississippi Delta region. DRA areas have high rates of disease, including cancers related to the human papillomavirus (HPV). HPV vaccination coverage in the DRA region has not been documented., Methods: We analyzed data for 63,299 adolescents aged 13 to 17 years in the National Immunization Survey-Teen, 2015-2017. We compared HPV vaccination initiation coverage estimates (≥1 dose) in the DRA region with coverage estimates in areas in the 8 Delta states outside the DRA region and non-Delta states. We examined correlates of HPV vaccination coverage initiation and reasons parents did not intend to vaccinate adolescents., Results: Vaccination rates in the DRA region (n = 2,317; 54.3%) and in Delta areas outside the DRA region (n = 6,028; 56.2%) were similar, but these rates were significantly lower than rates in non-Delta states (n = 54,954; 61.4%). Inside the DRA region, reasons for parents' vaccine hesitancy or refusal were similar to those expressed by parents in the Delta areas outside the DRA region. Some parents believed that the vaccine was not necessary or had concerns about vaccine safety., Conclusion: HPV vaccination coverage in the DRA region is similar to coverage in other Delta counties and parishes, but it is significantly lower than in non-Delta states. Activities to address parental concerns and improve provider recommendations for the vaccine in the DRA region are needed to increase HPV vaccination rates.

Disparities in HPV vaccination coverage by metropolitan statistical area (MSA) status were observed in the 2016 and 2017 National Immunization Survey - Teen (NIS-Teen). In 2017, HPV vaccination initiation (≥1dose) coverage was 11 percentage points lower for adolescents living in non-MSAs (mostly rural areas) and 7 percentage points lower among those living in MSA, non-principal cities (suburban areas) compared to those living in MSA, principal cities (mostly urban areas). In order to understand how this disparity has changed over time, we examined trends in HPV vaccine initiation by MSA status from 2013 to 2017. Weighted linear regression by survey year was used to estimate annual percentage point changes in HPV vaccination initiation. The five-year average annual percentage point increases in HPV vaccination initiation coverage were 5.2 in mostly urban areas, 4.9 for suburban areas, and 5.2 for mostly rural areas. Despite increases in each MSA area, coverage in mostly rural areas was consistently and significantly lower than coverage in mostly urban areas. Coverage was significantly lower among teens living in mostly rural areas regardless of poverty status, sex, and race/ethnicity except among black, non-Hispanic adolescents. There was no significant change in the magnitude of the disparity between mostly urban areas and mostly rural areas over time ( p = .98). A better understanding of the facilitators and barriers to HPV vaccination in mostly rural areas is needed to identify and implement targeted strategies to improve HPV vaccination coverage and reduce these disparities.

The 2016 and 2017 National Immunization Surveys-Teen (NIS-Teen) highlighted disparities in human papillomavirus (HPV) vaccination coverage by metropolitan statistical area (MSA) status. Coverage with ≥1 dose of HPV vaccine was significantly lower among teens in suburban and mostly rural areas than it was among those in mostly urban areas. Reasons underlying this disparity are poorly understood; this analysis sought to identify sociodemographic factors associated with not initiating the HPV vaccine series and to determine whether these factors differed by MSA status. Using NIS-Teen data for a sample of 41,424 adolescents from the 2016 and 2017 survey years, multivariate logistic regression was utilized to assess associations between various sociodemographic factors and non-initiation of the HPV vaccine series by MSA status. Adjusted prevalence ratios and 95% confidence intervals are reported. A secondary analysis assessed missed opportunities for HPV vaccination by MSA status and estimated what coverage could be if these missed opportunities had not occurred. Most factors associated with not receiving HPV vaccine were similar across all three MSAs, including living in the South, having a mother with some college education, not having an 11-12-year-old well-child visit, and not receiving a provider recommendation for vaccination. Others were associated with non-initiation of the HPV vaccine series in only specific MSAs. Teens in suburban areas (82.2%) were more likely to miss opportunities for HPV vaccination than those in mostly urban (79.3%) areas. Coverage with ≥1 dose of HPV vaccine in all three MSAs would be substantially higher if these missed opportunities had been eliminated.

Objective: To assess human papillomavirus (HPV) vaccination coverage among adolescents by provider recommendation status., Study Design: The 2011-2016 National Immunization Survey-Teen data were used to assess HPV vaccination coverage among male adolescents by provider recommendation status. Multivariable logistic analyses were conducted to evaluate associations between HPV vaccination and provider recommendation status., Results: HPV vaccination coverage among male adolescents increased from 8.3% in 2011 to 57.3% in 2016. Likewise, the prevalence of provider recommendation increased from 14.2% in 2011 to 65.5% in 2016. In 2016, HPV coverage was higher in male adolescents with a provider recommendation than in those without a provider recommendation (68.8% vs 35.4%). In multivariable logistic regression, characteristics independently associated with a higher likelihood of HPV vaccination included receipt of a provider recommendation, age 16-17 years, black or Hispanic race/ethnicity, any Medicaid insurance, ≥2 physician contacts in the previous 12 months, and urban or suburban residence. Participants with a mother with some college or a college degree, those with a mother aged 35-44 years, and those who did not have a well-child visit at age 11-12 years had a lower likelihood of HPV vaccination., Conclusions: Receiving a provider recommendation for vaccination was significantly associated with receipt of HPV vaccine among male adolescents, indicating that a provider recommendation for vaccination is an important approach to increase vaccination coverage. Evidence-based strategies, such as standing orders and provider reminders, alone or in combination with health system interventions, are useful for increasing provider recommendations and HPV vaccination coverage among male adolescents., (Published by Elsevier Inc.)

Routine human papillomavirus (HPV) vaccination is recommended at 11 or 12 years by the Advisory Committee on Immunization Practices. National Immunization Survey-Teen data were analyzed to evaluate, among girls, coverage with one or more doses of HPV vaccination, missed opportunities for HPV vaccination, and potential achievable coverage before 13 years. Results were stratified by birth year cohorts. HPV vaccination coverage before 13 years (≥1 HPV dose) increased from 28.4% for girls born in 1995 to 46.8% for girls born in 2000. Among girls born during 1999-2000 who had not received HPV vaccination before 13 years (57.2%), 80.1% had at least 1 missed opportunity to receive HPV vaccination before 13 years. Opportunities to vaccinate for HPV at age 11 to 12 years are missed. Strategies are needed to decrease these missed opportunities for HPV vaccination. This can be facilitated by the administration of all vaccines recommended for adolescents at the same visit., (© The Author(s) 2015.)

Background: In 2011, the Advisory Committee for Immunization Practices (ACIP) recommended routine use human papillomavirus (HPV) vaccine for male adolescents., Methods: We used the 2013 National Immunization Survey-Teen data to assess HPV vaccine uptake (≥1 dose) and series completion (≥3 doses). Multivariable logistic regression analysis and a predictive marginal model were conducted to identify independent predictors of vaccination among adolescent males aged 13 to 17 years., Results: HPV vaccination coverage with ≥1 dose was 34.6%, and series completion (≥3 doses) was 13.9%. Coverage was significantly higher among non-Hispanic blacks and Hispanics compared with non-Hispanic white male adolescents. Multivariable logistic regression showed that characteristics independently associated with a higher likelihood of HPV vaccination (≥1 dose) included being non-Hispanic black race or Hispanic ethnicity; having mothers who were widowed, divorced, or separated; having 1 to 3 physician contacts in the past 12 months; a well-child visit at age 11 to 12 years; having 1 or 2 vaccination providers; living in urban or suburban areas; and receiving vaccinations from >1 type of facility (P < .05). Having mothers with some college or college education, having a higher family income to poverty ratio, living in the South or Midwest, and receiving vaccinations from all sexually transmitted diseases/school/teen clinics or other facilities were independently associated with a lower likelihood of HPV vaccination (P < .05)., Conclusions: Following recommendations for routine HPV vaccination among male adolescents, uptake in 2013 was low in this population. Increased efforts are needed to improve vaccination coverage, especially for those who are least likely to be vaccinated., (Copyright © 2015 by the American Academy of Pediatrics.)

Routine immunization is recommended for adolescents aged 11-12 years by the Advisory Committee on Immunization Practices (ACIP) for protection against diseases including pertussis, meningococcal disease, and human papillomavirus (HPV)-associated cancers. To assess vaccination coverage among adolescents, CDC analyzed data collected regarding 20,827 adolescents through the 2014 National Immunization Survey-Teen (NIS-Teen). From 2013 to 2014, coverage among adolescents aged 13-17 years increased for all routinely recommended vaccines: from 84.7% to 87.6% for ≥1 tetanus-diphtheria-acellular pertussis (Tdap) vaccine dose, from 76.6% to 79.3% for ≥1 meningococcal conjugate (MenACWY) vaccine dose, from 56.7% to 60.0% and from 33.6% to 41.7% for ≥1 HPV vaccine dose among females and males, respectively.† Coverage differed by state and local area. Despite overall progress in vaccination coverage among adolescents, HPV vaccination coverage continues to lag behind Tdap and MenACWY coverage at state and national levels. Seven public health jurisdictions achieved significant increases in ≥1- or ≥3-dose HPV vaccination coverage among females in 2014, demonstrating that substantial improvement in HPV vaccination coverage is feasible.

The Advisory Committee on Immunization Practices (ACIP) recommends that adolescents routinely receive 1 dose of tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) vaccine, 2 doses of meningococcal conjugate (MenACWY) vaccine, and 3 doses of human papillomavirus (HPV) vaccine.* ACIP also recommends administration of "catch-up"† vaccinations, such as measles, mumps, and rubella (MMR), hepatitis B, and varicella, and, for all persons aged ≥6 months, an annual influenza vaccination. ACIP recommends administration of all age-appropriate vaccines during a single visit. To assess vaccination coverage among adolescents aged 13-17 years, CDC analyzed data from the 2013 National Immunization Survey-Teen (NIS-Teen).§ This report summarizes the results of that analysis, which show that from 2012 to 2013, coverage increased for each of the vaccines routinely recommended for adolescents: from 84.6% to 86.0% for ≥1 Tdap dose; from 74.0% to 77.8% for ≥1 MenACWY dose; from 53.8% to 57.3% for ≥1 HPV dose among females, and from 20.8% to 34.6% for ≥1 HPV dose among males. Coverage varied by state and local jurisdictions and by U.S. Department of Health and Human Services (HHS) region. Healthy People 2020 vaccination targets for adolescents aged 13-15 years were reached in 42 states for ≥1 Tdap dose, 18 for ≥1 MenACWY dose, and 11 for ≥2 varicella doses. No state met the target for ≥3 HPV doses.¶ Use of patient reminder and recall systems, immunization information systems, coverage assessment and feedback to clinicians, clinician reminders, standing orders, and other interventions can help make use of every health care visit to ensure that adolescents are fully protected from vaccine-preventable infections and cancers (5), especially when such interventions are coupled with clinicians' vaccination recommendations.
