RTS,S/AS01E vaccine defaults in Ghana: a qualitative exploration of the perspectives of defaulters and frontline health service providers

Abstract

Background While Ghana has a good track record in the Expanded Programme on Immunization, there are sub stantial challenges with regards to subsequent vaccinations, particularly after the frst year of life of the child. Given that the last dose of the RTS, S/AS01E vaccine against malaria is administered at 24 months, there is a high likelihood of default. Hence, it is imperative to understand the dynamics and reasons for the defaults to enable the develop ment of efective implementation strategies. This study explored why caregivers default on the RTS, S/AS01E vaccine from the perspective of health service providers and caregivers. Methods This study employed an exploratory, descriptive approach. Using a purposive sampling technique, caregiv ers who defaulted and health service providers directly involved in the planning and delivery of the RTS, S/AS01E vaccine at the district level were recruited. A total of fve health service providers and 30 mothers (six per FGD) par ticipated in this study. Data analysis was done using NVivo-12 following Collaizi’s thematic framework for qualitative analysis. The study relies on the Standards for Reporting Qualitative Research. Results Reasons for defaulting included the overlap of timing of the last dose and the child starting school, dis respectful attitudes of some health service providers, concerns about adverse side efects and discomforts, travel out of the implementing district, the perception that the vaccines are too many, and lack of support from partners. Conclusion To reduce the occurrence of defaulting on the RTS, S/AS01E vaccine programme, stakeholders must reconsider the timing of the last dose of the vaccine. The schedule of the RTS, S/AS01E vaccine should be aligned with the established EPI schedule of Ghana. This will signifcantly limit the potential of defaults, particularly for the last dose. Also, the fndings from this study underscore a need to encourage male partner involvement in the RTS, S/AS01E vaccine programme. Health promotion programmes could be implemented to raise caregivers’ awareness of potential adverse reactions and discomforts—this is necessary to prepare the caregiver for the vaccine process psychologically.
