Abstract

Vaccination is the most effective intervention for the primary prevention of COVID-19. Several studies have been conducted in sub-Saharan African countries on the acceptance and associated factors of COVID-19 vaccine. This review and meta-analysis aimed to recapitulate the pooled magnitude of vaccine acceptance and its favoring factors in sub-Saharan African countries. PUBMED, MEDLINE, Science Direct, Web of Science, and SCOPUS were the main databases searched from 15 March to 5 June 2022; and all the articles written in the English language were included. Also, some articles were retrieved from biomedical peer-reviewed journal sites and Google scholar. The quality of thirty-five selected articles was evaluated using an adapted scale for evaluating cross-sectional studies based on the Newcastle-Ottawa Scale. The result of the review and meta-analysis revealed that COVID-19 vaccine acceptance rate varied across studies. In a pooled analysis, factors such as; higher-level perception of infection risk (OR (95% CI (2.7 (2.1, 3.4))), perceived vaccine safety (13.9 (9.2, 20.9)), virus-related good knowledge (2.7 (2.3, 3.2)) and appropriate attitude (5.9 (4.4, 7.8)), adherence to safety precautions (5.5 (4.8, 6.2)), and infection experience (4.4 (2.8, 6.9)) were positively affected the COVID-19 vaccine acceptance. Also, vaccine acceptance was found to be high among males and chronically ill individuals. Thus, understanding factors that enhance vaccine acceptance would support planners to augment vaccine uptake in the region.
