%X Bangladesh has fully vaccinated 76 per 100 population against COVID-19. However, ensuring higher coverage in vulnerable sites is subject to various challenges. We report the COVID-19 vaccine uptake and its correlates among the adults residing




in two vulnerable sites in Bangladesh. We conducted a cross-sectional study between August and September 2022 in two sites with a high prevalence of in- and out-migration. Duaripara, a slum in northeast Dhaka, was selected as the in-migration site. Tala, a disaster-prone




sub-district located in southwest Satkhira, was selected as the out-migration site. We surveyed 2502 adults (1239 from Duaripara; 1263 from Tala) from 1211 randomly selected households. We reported coverage and examined associations




between the uptake and background characteristics using Poisson, and Two-part regression models. Additionally, we checked for spatial autocorrelation to assess equitable distribution geographically. The coverage for the first and second doses of the COVID-19 vaccine were about




91% and 80.3% in Duaripara, and 96.6% and 92.2% in Tala, respectively. For the third dose, it was about 14% in Duaripara and 52.4% in Tala. For Tala, the uptake was significantly associated with age, education, and occupation. Interestingly,




it was associated positively with television access (Incidence rate ratio: 1.04, p-value = 0.01) and negatively with smart-phone access (IRR: 0.96, p-value = 0.04). Respondents who temporarily migrated were more likely to remain unvaccinated




(IRR: 0.90, p-value <0.001). For Duaripara, age and occupation were associated with the uptake. For both sites, the uptake was neither associated with income or wealth, nor correlated with geographical location, indicating equitable distribution.




The credit for high COVID-19 vaccine coverage in Bangladesh dates back to its long history of implementing immunization programs through community mobilization and creating demand through health education. However, full vaccination is




essential to reduce COVID-19-related deaths. Health authorities need to pay special attention to vulnerable sites.
