In addition to being home to more than seven million HIV-infected individuals, South Africa also has a high burden of COVID-19 and related comorbidities worldwide. We aimed to identify the most influential "beliefs" and "attitudes" on vaccine decision-making behavior.
This study used panel data from cross-sectional surveys.
We used the data from Black South Africans who participated in the "COVID-19 Vaccine Surveys" (November 2021 and February/March 2022) in South Africa. Besides standard risk factor analysis, such as multivariable logistic regression models, we also used the modified version of population attributable risk percent and estimated the population-level impacts of beliefs and attitudes on vaccine decision-making behavior using the methodology in multifactorial setting.
A total of 1399 people (57% men and 43% women) who participated in both surveys were analyzed. Of these, 336 (24%) reported being vaccinated in survey 2. Overall low perceived risk, concerns around efficacy, and safety were identified as the most influential factors and associated with 52%-72% (<40 years) and 34%-55% (40+ years) of the unvaccinated individuals.
Our findings highlighted the most influential beliefs and attitudes on vaccine decision-making and their population-level impacts, which are likely to have significant public health implications exclusively for this population.
南非不仅是 700 多万艾滋病毒感染者的家园，也是全球 COVID-19 和相关合并症负担沉重的国家。我们旨在确定对疫苗决策行为最有影响的“信念”和“态度”。
本研究使用了来自横断面调查的面板数据。
我们使用了参与南非“COVID-19 疫苗调查”（2021 年 11 月和 2022 年 2 月/3 月）的南非黑人的数据。除了多变量逻辑回归模型等标准风险因素分析外，我们还使用了人群归因风险百分比的修正版本，并使用多因素环境中的方法估计信念和态度对疫苗决策行为的人群水平影响。
共分析了 1399 名（57%为男性，43%为女性）参加了两次调查的人。其中，336 人（24%）在调查 2 中报告已接种疫苗。总体而言，低感知风险、对疗效和安全性的担忧被认为是最有影响的因素，与 52%-72%（<40 岁）和 34%-55%（40 岁以上）的未接种人群有关。
我们的研究结果强调了对疫苗决策最有影响的信念和态度及其对人群水平的影响，这可能对这一人群产生重大的公共卫生影响。
