This survey was conducted as part of the Gavi Full Country Evaluation (FCE) project in Bangladesh. Gavi FCEs are prospective studies covering the period 2013-2016 that aim to assess the barriers to and drivers of immunization program performance. The Bangladesh FCE focused on selected locations stratified by urban/rural and low/high immunization coverage performance areas. It was conducted in one rural district and one city corporation each in the divisions of Sylhet and Rajshahi. This survey collected information from patient exit interviews conducted with caregivers of children 9 months to 15 years of age immediately following their measles-rubella vaccination. Topics covered include sociodemographic characteristics of the caretaker; patient experiences at the facility; patient opinions of the experience; and knowledge, attitudes and practice regarding measles and rubella immunizations, as well as knowledge of measles and rubella symptoms, prevention, and treatment.
