Prevalence & correlates of COVID-19 vaccine hesitancy in a rural community of Bengaluru district, southern India: A preliminary cross-sectional study

ABSTRACT

Background & objectives: Studying vaccine hesitancy is important for helping improve vaccine coverage against COVID-19. The objective of this study was to assess the prevalence and correlates of COVID-19 vaccine hesitancy in a rural community in India. Methods: A cross-sectional study of all adults aged over 18 yr was undertaken during July-August 2021, in a village outside Bengaluru city in southern India. Results: In our study, 68.7 per cent of the eligible 297 adult population accepted vaccination immediately, another 9.4 per cent hesitated but accepted vaccination without delay, a further 10.4 per cent delayed their vaccination and the remaining 11.5 per cent refused vaccination. The prevalence (95% confidence interval) of vaccine hesitancy was 21.9±4.8 per cent. Full vaccination was higher among males (76%) compared to females (58%, P<0.001). Those who hesitated and delayed vaccination (converts) were more likely to be from a nuclear family, whereas those who refused the vaccine were from a joint/three-generation family. Those who refused vaccination were adversely influenced by social media predominantly as also their religious/cultural beliefs and distrust on the pharmaceutical industry. Those who delayed but accepted vaccination were positively influenced by healthcare professionals and others who had accepted the vaccine recently. Geographic factors, cost of vaccine, and mode of administration were not the major concerns. Interpretation & conclusions: Vaccine uptake is a continuum. Our study helped identify the characteristics of those who delayed vaccination versus those who refused vaccination. This will help policymakers, programme managers and healthcare professionals to focus priority action on population subgroups for improving individual- and population-level protection.
