"I would have to sell things in order to get the money": A qualitative exploration of willingness to pay for the RTS,S/AS01 malaria vaccine in the Volta region, Ghana.

backgroundMalaria morbidity and mortality remain a challenge in Ghana. A promising childhood vaccine is being piloted in Ghana, however with the loss of its low-income status, Ghana is losing associated donor co-funding. User fees have been considered an alternative financing method, so this study utilised qualitative methods and explored caregivers' willingness to pay for the malaria vaccine (RTS,S/AS01) to inform future service provision.

methodsThe study design was cross-sectional. Twenty in-depth interviews were conducted between February 2020 and March 2020 amongst a purposive sample of caregivers of RTS,S/AS01 eligible children, in the Volta region, Ghana. Interviews were audio-recorded and transcribed into English Language. Thematic analysis followed, using NVIVO12 to organise this data.

resultsCaregivers could distinguish between RTS,S/AS01 and routine vaccines and were willing to pay median GH₵5 (US$0.94), interquartile range GH₵3.75-5 (US$0.71-0.94) per dose of RTS,S/AS01. The maximum amount participants were willing to pay per dose was GH₵10 (US$1.88), interquartile range GH₵6-10 (US$1.13-1.88). Caregivers mentioned that they would work more to cover this cost because they were happy with services rendered to them during the RTS,S/AS01 pilot phase, and preferred vaccines over vector control measures. The results suggest that a willingness to pay was based on beliefs that the vaccine is fully effective. Although no participant declared that they would be unwilling to pay hypothetical user fees, there were still widespread concerns about affordability, with the majority feeling that the government should be responsible to pay for RTS,S/AS01.

conclusionsParticipants expressed a willingness to pay due to an appreciation of vaccines, shaped by personal experiences with immunisations and disease. Participants' average income was lower than the national average, potentially affecting the perceived affordability of RTS,S/AS01. Because of the belief that RTS,S/AS01 is fully effective, caregivers may pay less attention to other preventative measures, thus unintentionally undermining malaria vector control.
