COVID-19 vaccine booster uptake among healthcare workers in Bangladesh: predictors, challenges, and lessons from a low-income setting.
Article in Tropical medicine and health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundHealthcare workers (HCWs) remain at an elevated risk of SARS-CoV-2 infection due to occupational exposure and waning vaccine-induced immunity. We conducted a longitudinal study to estimate cumulative uptake, incidence, and factors associated with COVID-19 booster dose uptake among Bangladeshi HCWs.
methodsBetween March 2021 and December 2023, we followed 3099 HCWs recruited from 20 healthcare facilities across four divisions of Bangladesh. At enrollment, information was collected on sociodemographic and clinical characteristics, prior SARS-CoV-2 infection, and COVID-19 vaccination history. Booster uptake status was updated biweekly. Multivariable Cox proportional hazards regression models were used to estimate adjusted hazard ratios (aHRs) for predictors of booster uptake.
resultsDuring follow-up, 1964 (63.4%) HCWs received at least one COVID-19 booster dose. However, uptake of the 2nd booster dose was low (6%). The incidence of booster uptake was 54.5 per 100 person-years (95% CI 50.0-59.5). The hazard of booster uptake was higher among HCWs with prior SARS-CoV-2 infection (aHR = 1.13; 95% CI 1.01-1.26) and among those working in both COVID-19 and general wards (aHR = 1.36; 95% CI 1.22-1.53). In contrast, prior adverse events following the primary series (aHR = 0.36; 95% CI 0.32-0.41) were associated with a lower hazard of booster uptake.
conclusionsAlthough more than half of HCWs received a booster, uptake declined with repeated dosing. Variations in the hazard of uptake by occupational exposure, prior infection, and adverse events reflect changing perceptions of risk and experiential factors in addition to access. Strengthening institutional vaccination policies and addressing behavioral barriers may thus support timely booster uptake among HCWs.
