Hesitant or not: A cross-sectional study of socio-demographics, conspiracy theories, trust in public health information, social capital and vaccine hesitancy among older adults in Ghana

Vaccination is an effective strategy to reduce the coronavirus disease 2019 (COVID-19) burden, but its effectiveness hinges on timely vaccine uptake. Addressing concerns among vaccine-hesitant individuals is critical to preventing the immunization program from failing. This study analyzes the determinants of vaccine hesitance among older adults (aged 50 years and older) in Ghana. We adopted a cross-sectional survey with a quantitative approach that accessed data from 400 older adults from the Accra and Kumasi metropolitan areas using purposive and snowball sampling techniques. Multivariate logistic regressions were used to estimate the socio-demographic, social capital, conspiracy theories about COVID-19, and public health information factors associated with vaccine hesitance within the sample. The study found that only minority (5%) of respondents had been vaccinated, with 79% indicating willingness to be vaccinated. The study found that females (AOR: 0.734, CI: 0.019–0.036, p = .027) and those who have retired (AOR: 0.861, CI: 0.003–0.028, p = .034) were significantly less likely to engage in COVID-19 vaccine hesitance. Furthermore, the study revealed that participants who trust public health information (AOR: 0.065, CI: 0.022–0.049, p = .031) and have social capital (AOR: 0.886, CI: 0.017–0.032, p = .001) were significantly less likely to present COVID-19 vaccine hesitance. Finally, participants who believe in conspiracy theories about COVID-19 and vaccines (AOR: 3.167, CI: 1.021–2.043, p = .004) were significantly more likely to engage in COVID-19 vaccine hesitance. Efforts to convey vaccination benefits and address issues through evidence-based information are needed to strengthen and preserve the public’s trust in vaccines in Ghana.
