Most African countries report low COVID-19 vaccination rates (Msellati et al., 2022; WHO Africa; 2020). This study focuses on factors associated with vaccine hesitancy specifically in the country of Cameroon. Social media use and medical mistrust have been suggested as key variables that may increase vaccine hesitancy. Adopting the information-related perspective guided by the risk information seeking and processing model, the current research explored how social media use and medical mistrust are related to vaccine hesitancy among Cameroonians. Survey results from a sample of 1,000 Cameroonians fielded in early 2022 showed that social media use and medical mistrust were positively associated with belief in misinformation related to the COVID-19 vaccine. Belief in misinformation about the COVID-19 vaccine was negatively associated with perceived information insufficiency. A positive relationship between perceived information insufficiency and information seeking, as well as a negative relationship between information seeking and vaccine hesitancy were also found. Theoretical and practical implications are discussed.

大多数非洲国家报告的 COVID-19 疫苗接种率较低（Msellati 等人，2022 年；世界卫生组织非洲分部；2020 年）。这项研究的重点是与疫苗犹豫相关的因素，特别是在喀麦隆国家。社交媒体的使用和医疗不信任被认为是可能增加疫苗犹豫的关键变量。本研究采用以风险信息寻求和处理模型为指导的信息相关视角，探讨了社交媒体的使用和医疗不信任与喀麦隆人的疫苗犹豫之间的关系。2022 年初对 1,000 名喀麦隆人进行的抽样调查结果显示，社交媒体的使用和医疗不信任与对 COVID-19 疫苗相关错误信息的信念呈正相关。对有关 COVID-19 疫苗的错误信息的信念与感知到的信息不足呈负相关。还发现感知信息不足与信息寻求之间存在正相关关系，而信息寻求与疫苗犹豫之间存在负相关关系。讨论了理论和实践意义。
