Vaccination coverage rates and predictors of HPV vaccination among eligible and non-eligible female adolescents at the Brazilian HPV vaccination public program

In February 2018, recognizing the suboptimal rates of human papillomavirus (HPV) vaccination in the United States, the assistant secretary for health of the US Department of Health and Human Services charged the National Vaccine Advisory Committee (NVAC) with providing recommendations on how to strengthen the effectiveness of national, state, and local efforts to improve HPV vaccination coverage rates. In the same month, the NVAC established the HPV Vaccination Implementation Working Group and assigned it to develop these recommendations. The working group sought advice from federal and nonfederal partners. This NVAC report recommends ways to improve HPV vaccination coverage rates by focusing on 4 areas of activity: (1) identifying additional national partners, (2) guiding coalition building for states, (3) engaging integrated health care delivery networks, and (4) addressing provider needs in rural areas.

Background: Since 2007, all Canadian provinces and territories have had a publicly funded program for vaccination against human papillomavirus (HPV) infection. The objective of this study was to describe the evolution of these vaccination programs. Methods: This was a targeted literature review of public HPV vaccination programs and vaccination coverage rates, based on information provided by jurisdictional public health authorities. Results: HPV vaccination of schoolgirls began in school years 2007/08 to 2010/11 with three doses of the quadrivalent HPV vaccine in all provinces except Quebec, which started with two doses. By 2018/19, all jurisdictions were vaccinating with two doses of the nonavalent vaccine in both girls and boys, except Quebec, which used a mixed vaccination schedule with one dose of the nonavalent and one dose of the bivalent vaccines. Public HPV vaccination programs in most provinces include after-school catch-up vaccination. Immunocompromised or other high-risk individuals are eligible for the HPV public vaccination program in most provinces, but policies vary by jurisdiction. In 2017/18, vaccination coverage rates in provincial HPV school-based programs varied from 62% in Ontario to 86% in Prince Edward Island in girls and from 58% in Ontario to 86% in Prince Edward Island in boys. Conclusions: Since their introduction, Canadian school-based HPV public vaccination programs have evolved from a three-dose to a two-dose schedule, from a quadrivalent to a nonavalent vaccine, and from a girls-only to a gender-neutral policy. Vaccination coverage rates have varied markedly and only Prince Edward Island and Newfoundland/Labrador have maintained rates exceeding 80%.

Vaccine Initiation

Native Hawaiian and Pacific Islander (NHPI) adults bear a disproportionate burden of certain human papillomavirus (HPV)-associated cancers. In 2015, data from the National Health Interview Survey (NHIS) showed vaccination coverage among adults by racial and ethnic groups; however, coverage data for NHPI adults were unavailable. In this study, we estimated the initiation and completion of HPV vaccination and assessed the factors associated with vaccination among NHPI adults aged 18 to 26 years in the United States. We analyzed public data files from the 2014 NHPI NHIS (n = 1204). We specified sampling design parameters and fitted weighted logistic regression models to calculate the odds of HPV vaccine initiation. We developed a directed acyclic graph to identify a minimally sufficient set for adjustment and adjusted for insurance coverage (for education and ethnicity) and doctor visit (for insurance coverage, earnings, ethnicity, and sex). Overall, 24.9% and 11.5% of NHPI adults had initiated and completed the HPV vaccination series, respectively. Weighted logistic regression models elucidated that the odds of HPV vaccine initiation were higher for females (weighted odds ratio = 5.4; 95% confidence interval = 2.8-10.4) compared with males. Low vaccination coverage found among NHPI adults provides an opportunity for targeted programs to reduce the burden of HPV-associated cancers.

Abstract Background Previous studies on adult vaccination coverage found inter-state variability that persists after adjusting for individual demographic factors. Assessing the impact of state-level factors may help improve uptake strategies. This study aimed to: • Update previous estimates of state-level, model-adjusted coverage rates for influenza; pneumococcal; tetanus, diphtheria, and acellular pertussis (Tdap); and herpes zoster (HZ) vaccines (individually and in compliance with all age-appropriate recommended vaccinations) • Evaluate effects of individual and state-level factors on adult vaccination coverage using a multilevel modeling framework. Methods Behavioral Risk Factor Surveillance System (BRFSS) survey data (2015–2017) were retrospectively analyzed. Multivariable logistic regression models estimated state vaccination coverage and compliance using predicted marginal proportions. BRFSS data were then combined with external state-level data to estimate multilevel models evaluating effects of state-level factors on coverage. Weighted odds ratios and measures of cluster variation were estimated. Results Adult vaccination coverage and compliance varied by state, even after adjusting for individual characteristics, with coverage ranging as follows: • Influenza (2017): 35.1–48.1% • Pneumococcal (2017): 68.2–80.8% • Tdap (2016): 21.9–46.5% • HZ (2017): 30.5–50.9% Few state-level variables were retained in final multilevel models, and measures of cluster variation suggested substantial residual variation unexplained by individual and state-level variables. Key state-level variables positively associated with vaccination included health insurance coverage rates (influenza/HZ), pharmacists’ vaccination authority (HZ), presence of childhood vaccination exemptions (pneumococcal/Tdap), and adult immunization information system participation (Tdap/HZ). Conclusion Adult vaccination coverage and compliance continue to show substantial variation by state even after adjusting for individual and state-level characteristics associated with vaccination. Further research is needed to assess additional state or local factors impacting vaccination disparities.

National Immunization Survey

Since 1994, the Centers for Disease Control and Prevention has funded the National Immunization Survey (NIS), a large telephone survey used to estimate vaccination coverage of U.S. children aged 19–35 months. The NIS is a two-phase survey that obtains vaccination receipt information from a random-digit-dialed survey, designed to identify households with eligible children, followed by a provider record check, which obtains provider-reported vaccination histories for eligible children. In 2006, the survey was expanded for the first time to include a national sample of adolescents aged 13–17 years, called the NIS-Teen. This article summarizes the methodology used in the NIS-Teen. In 2008, the NIS-Teen was expanded to collect state-specific and national-level data to determine vaccination coverage estimates. This survey provides valuable information to guide immunization programs for adolescents.

The Impact

The Advisory Committee on Immunization Practices recommends routine human papillomavirus (HPV) immunization for 11- to 12-year-old adolescents. In 2008, Louisiana required the school boards to distribute HPV vaccine information to parents or guardian of students in Grades 6 to 12. This article investigates the impact of this policy on HPV vaccination among 13- to 17-year-old female adolescents using National Immunization Survey-Teen (NIS-Teen) data. Drawing on the data from the 2008 to 2012 NIS-Teen, we compared the difference in proportions of females who have been vaccinated before and after the policy. Using difference-indifference estimation, we explored the change in vaccination rates before and after the policy implementation in Louisiana compared with Alabama and Mississippi, two states that did not have such a policy in place. The difference-in-differences estimates for HPV vaccination were not significant. Physician recommendation for HPV vaccination was significantly associated with vaccination among females in Louisiana and Alabama (adjusted odds ratio [aOR] = 7.74; 95% confidence interval [CI; 5.22, 11.5]), and for those in Louisiana and Mississippi (aOR = 7.05; 95% CI [4.6, 10.5]). Compared to the proportion of female adolescents who had received physician recommendation in Alabama or Mississippi, the proportion in Louisiana did not increase significantly in the postpolicy period. HPV vaccination rates did not increase significantly in Louisiana compared to Alabama or Mississippi following the implementation of the policy. Despite Louisiana’s policy, physician recommendation remains the key determinant of HPV vaccination. HPV vaccine awareness does not necessarily result in HPV vaccination.
