Evidence on factors influencing HPV vaccine implementation in South Asia: A scoping review

Abstract

Cervical cancer is a significant public health concern globally, with low and middle-income countries bearing the highest burden, specifically the South Asian region. Therefore, the current scoping review aimed to highlight the factors influencing the implementation of human papillomavirus (HPV) vaccination in South Asia. Adopting the 'Arksey and O'Malley and Levac et al.' methodology, multiple electronic databases were searched to identify relevant records. The results were narratively synthesised and discussed, adopting the Consolidated Framework for Implementation Research (CFIR) model. We identified 527 records, which were assessed for eligibility based on title, abstract, and full text by three reviewers, followed by data extraction of 29 studies included for analysis in the review. Implementing HPV vaccination programs in South Asia faces various challenges, such as economic, health system, financial, health literacy, and sociocultural factors that hinder their successful implementation. To successfully implement the vaccine, a tailored risk communication strategy is necessary for these countries. Knowledge gained from the experience of South Asian nations in implementing the HPV vaccine can assist in policymaking in similar healthcare for advancing the implementation of HPV vaccination.
