Abstract:
Hesitancy to Covid-19 vaccine is a global challenge despite the compelling evidence of the value
of vaccine in preventing disease and saving lives. It is suggested that context-specific strategies
can enhance acceptability and decrease hesitancy to Covid-19 vaccine. Hence, the study
determined uptake and determinants of Covid-19 vaccine following a sustained voluntary
vaccination drive by Kenyan government. Method
We conducted institution based cross-sectional survey of 1244 elderly persons aged 58 to 98 years
in the months of January, February and March, 2022. A multinomial logistic regression analysis
was used to investigate determinants of Covid 19 vaccine uptake. The predictor variables included
socioeconomic and demographic characteristics, convenience and ease of access of the vaccine,
collective responsibility, complacency and the three dimensions of confidence; trust in safety, trust
in decision makers and delivery system. The findings are reported as the adjusted odd ratio (AOR)
at 95% confidence interval (CI). Significant level was considered at p <0.05.
ResultThe results from the multinomial logistic regression analysis indicated that advanced age and
presence of chronic disease were associated with increased odds of doubt on Covid 19 vaccine,
while long distance from vaccination centers was associated with increased odds of delay in
vaccination.
Conclusion
Overall, the findings of this study have provided valuable insights into the factors influencing
vaccine hesitancy among the elderly population in Kenya and will inform the development of
targeted interventions to increase vaccine acceptance and uptake in this population.
