COVID-19 vaccine coverage in most countries in Africa remains low. Determinants of uptake need to be better understood to improve vaccination campaigns. Few studies from Africa have identified correlates of COVID-19 vaccination in the general population. We surveyed adults at 32 healthcare facilities across Malawi, purposively sampled to ensure balanced representation of adults with and without HIV. The survey, informed by the World Health Organization's Behavioural and Social Drivers of Vaccination Framework, asked about people's thoughts and feelings about the vaccine, social processes, motivation to vaccinate, and access issues. We classified respondents' COVID-19 vaccination status and willingness to vaccinate, and used multivariable logistic regression to assess correlates of these. Among 837 surveyed individuals (median age was 39 years (IQR 30-49) and 56% were female), 33% were up-to-date on COVID-19 vaccination, 61% were unvaccinated, and 6% were overdue for a second dose. Those up-to-date were more likely to know someone who had died from COVID-19, feel the vaccine is important and safe, and perceive pro-vaccination social norms. Despite prevalent concerns about vaccine side effects, 54% of unvaccinated respondents were willing to vaccinate. Access issues were reported by 28% of unvaccinated but willing respondents. Up-to-date COVID-19 vaccination status was associated with positive attitudes about the vaccine and with perceiving pro-vaccination social norms. Over half of unvaccinated respondents were willing to get vaccinated. Disseminating vaccine safety messages from trusted sources and ensuring local vaccine availability may ultimately increase vaccine uptake.
在大多数非洲国家,COVID-19 疫苗接种覆盖率仍然很低。为了改善疫苗接种活动,需要更好地了解疫苗接种的决定因素。很少有来自非洲的研究确定了普通人群中 COVID-19 疫苗接种的相关因素。我们在马拉维的 32 个医疗保健设施中对成年人进行了调查,采用有目的抽样方法,以确保有 HIV 的成年人和没有 HIV 的成年人的代表性均衡。该调查以世界卫生组织的疫苗接种行为和社会驱动因素框架为依据,询问了人们对疫苗的想法和感受、社会过程、接种疫苗的动机和获得疫苗的问题。我们将受访者的 COVID-19 疫苗接种状况和接种意愿进行分类,并使用多变量逻辑回归评估这些因素的相关性。在接受调查的 837 人中(中位数年龄为 39 岁(IQR 30-49),56%为女性),33%的人已完成 COVID-19 疫苗接种,61%的人未接种疫苗,6%的人第二剂疫苗逾期。那些已完成疫苗接种的人更有可能认识因 COVID-19 而死亡的人,认为疫苗很重要且安全,并认为存在支持疫苗接种的社会规范。尽管普遍担心疫苗的副作用,但 54%的未接种疫苗但愿意接种疫苗的受访者表示愿意接种。28%愿意接种疫苗但未接种疫苗的受访者报告存在接种疫苗的障碍。及时接种 COVID-19 疫苗与对疫苗的积极态度以及对支持疫苗接种的社会规范的认识有关。超过一半的未接种疫苗的受访者愿意接种疫苗。从可信赖的来源传播疫苗安全性信息并确保当地疫苗供应,最终可能会提高疫苗接种率。
