Among Bangladeshi adults, COVID-19 vaccine hesitancy was common (41.1%), and the Theory of Planned Behavior explained more variance than HBM or 5C models.

41.1% prevalence of COVID-19 vaccine hesitancy.
As a result, we found a 41.1% prevalence of the COVID-19 vaccine hesitancy among our study respondents, a significantly higher estimate than found by Kabir et al.
TPB explained 43% of hesitancy variance (adjusted R²=0.43).
The second model shows that 43% of the variance in COVID-19 vaccine hesitancy was explained by the TPB (adjusted R 2 = 0.43) ().
Key findings
Hesitancy prevalence was 41.1%; TPB explained 43% of variance (highest predictive power) with all four TPB components significant; key HBM constructs also predicted hesitancy.
Methodology
Researchers surveyed adults in Bangladesh and compared how HBM, TPB, and 5C psychological antecedents predicted COVID-19 vaccine hesitancy after covariate adjustment.
Limitations
Whether theory-based campaigns will raise uptake, or causal effects—design is cross-sectional prediction.
