AI Article Synopsis
- The study evaluates a school-based HPV vaccination program in Indaiatuba, Brazil, over a two-year period to assess its effectiveness and implementation.
- The program, initiated in 2018, targeted children aged 9 to 10, resulting in a significant increase in vaccination coverage from 16.1% in 2017 to 50.5% in 2018, despite some challenges.
- The conclusion highlights that while the program successfully increased overall vaccination rates, it faced obstacles from competing health demands, necessitating improved strategies for future efforts.
Article Abstract
Objective: The present study assesses the implementation and the impact after 2 years of a school-based (HPV) vaccination program in a Brazilian city.
Methods: A prospective study assessing the implementation of the program, offering quadrivalent HPV vaccine in two annual doses to girls and boys aged from 9 to 10 years old. The program was started in the city of Indaiatuba, state of São Paulo, Brazil, in 2018, and had authorization from the National Immunization Program. The number of HPV vaccine first doses applied and the coverage in 2018 was calculated and compared to the year 2017. There were described events that have influenced the results.
Results: The program invited 4,878 children through schools (87.1% of the target population), and 7.5% refused vaccination. Several concurrent events required or competed for health professionals of the vaccination teams. The coverage of the first dose (between 9 and 10 years old) was 16.1% in 2017 and increased to 50.5% in 2018 ( < 0.0001). The first dose in all ages increased 78% in 2018 compared with 2017 (6,636/3,733). Competing demands over the program continued in 2019, and the first dose coverage dropped (26.9%). For 2020, a municipal law instituted school-based vaccination and the creation of dedicated teams for vaccination, and these strategies are waiting to be tested.
Conclusion: School-based annual HPV vaccination in children between 9 and 10 years old was feasible and increased vaccination coverage, regardless of gender, although the program was vulnerable to competing events.

This study evaluates the association between immunization program (IP) activities aimed at increasing HPV vaccination among adolescents and their impact on initiation rates. Our data sources are: (i) 2016 AIM Annual Survey and (ii) 2019 National Immunization Survey-Teen. We estimated the prevalence of HPV vaccine initiation using a multilevel Poisson model, combining state-level IP data and individual characteristics of adolescents.

Background: All for Them is a theory-based and evidence-informed multilevel, multicomponent program delivered through schools to increase HPV vaccination among medically underserved youth across Texas. Given the potential logistical challenges of program implementation, understanding how to best support the implementation and sustainment of the program is critical. The overall goals of this study are twofold: 1) develop a multifaceted implementation strategy, Implementing All for Them (IM-AFT); and 2) evaluate the impact of IM-AFT on implementation outcomes for schools and healthcare providers to successfully implement All for Them in their respective settings.

Methods: Six electronic databases were searched for quantitative articles published between 1 September 2006 and 20 February 2023, which were representative of the general population, with individual-level data on routine school-based vaccination (with >50% coverage) and sociodemographic measures. Titles, abstracts and full-text articles were screened for eligibility criteria and assessed for bias.

Introduction: To address the cervical cancer burden globally, the World Health Organization and European Union released strategies to facilitate HPV-related cancers prevention, including cervical cancer elimination. This research assessed European country level readiness to achieve cervical cancer elimination by adhering to such strategies.
Areas Covered: Readiness for cervical cancer elimination was assessed across a range of guiding questions relevant to three defined key domains: vaccination, screening, and treatment, each with two sub-domains focusing on decision making and implementation efforts.
