 This study examined the factors associated with childhood vaccination coverage in Bangladesh, and found that it increased significantly from 2011 to 2017 to 18. Factors such as higher maternal education, higher family wealth index, and older age were associated with higher vaccination coverage. Additionally, Ranker Division had the greatest increase in vaccination coverage from 2011 to 2014, while Silvit Division had the largest increase from 2014 to 2017 to 18. Policies should focus on improving access to healthcare services, especially for those living in rural areas or with lower socioeconomic status. Additionally, efforts should be made to ensure that all mothers have access to adequate prenatal care, which can help ensure that their children are fully vaccinated.
