Globally, the COVID-19 vaccine uptake is increasing, but slowly among older adults residing in lower and middle-income countries, including Nigeria. Following this, we explored the perceived views of older adults on the uptake of the COVID-19 vaccine in Nigeria. We adopted a qualitative descriptive study design and purposively selected and interviewed 16 retirees of older adults. Data were analyzed using conventional content analysis. Findings show that older adults' willingness to receive the COVID-19 vaccine was dissuaded by their past experiences with the government, religion, and Western media, including affordability and accessibility problems related to vaccination campaigns. Findings also show that the uncertainty about the COVID-19 virus existence and perceptions about COVID-19 vaccine risks influence older adults' decisions regarding vaccine uptake. Finally, older adults' views on getting vaccinated for COVID-19 were positively influenced by the trust they placed in their physicians and other members of their healthcare system. The government should incentivize healthcare workers to serve as a nudge to increase COVID-19 vaccine uptake among older adults in Nigeria., Competing Interests: Conflict of InterestThe authors declare no conflict of interest in this study., (© The Author(s), under exclusive licence to Springer Nature B.V. 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.) more...
