Abstract A096: Stakeholders’ perceptions on the impact of the COVID-19 pandemic on the implementation of the HPV vaccine school-entry requirement in Puerto Rico

Background: The human papillomavirus (HPV) vaccine is a cancer prevention tool, yet vaccination coverage among adolescents remains suboptimal in the United States. Research shows significant disparate incidence and mortality rates of HPV-related cancers in Puerto Rico (PR). In 2018, the PR Department of Health (DOH) enacted an HPV vaccine school-entry requirement for adolescents 11 to 12 years old, and on August 2020 extended the requirement to include adolescents up to 16 years old. Amid the COVID-19 pandemic in the US, during March-August 2020, national data showed that HPV vaccine uptake rates decreased about 75%. Public health measures, such as stay-at-home orders, may have caused this decline by limiting access to preventive services. Our study explored, using a qualitative assessment, the impact of the COVID-19 pandemic on the implementation of the HPV vaccine school-entry requirement in PR. Methods: We conducted 26 interviews with stakeholders from schools, DOH employees, Department of education staff, health providers, and community-based organizations from 08/2021-03/2022. Interviews were recorded and transcribed in Spanish. Data were analyzed using applied thematic techniques by two trained coders using Atlas-ti 8. We discussed eight of these interviews among the team to identify major barriers related to the HPV school-entry implementation during the pandemic. Results: Our analysis identified the following preliminary emergent themes including: (1) lockdown limitations and access barriers to the vaccine and (2) shifting immunization priorities. Most participants noted that the March 2020 lockdown limited parents’ ability to get their kids vaccinated and for schools to monitor the vaccine requirements; however, as vaccination centers and schools re-opened, gradually, vaccination processes increased. Participants described how during the pandemic, public health agencies prioritized the COVID-19 vaccine missing other vaccines that are required for school-entry, including the HPV vaccine. Discussion: Continuation of the implementation of the HPV vaccine school-entry requirement was challenging during early stages of the pandemic due to public health measures enacted to stop the spread of COVID-19. Moreover, once the COVID-19 vaccine was available, public heath vaccination priorities shifted. Nonetheless these barriers, efforts to increase HPV vaccine to pre-pandemic rates should continue, including providing educational support to parents, increase
