| Public title | Indonesia Routine Immunization and New Vaccines Vaccination Coverage Survey 2024-2025 |
| Background | In 2019, Indonesia conducted a Data Quality Review of Immunization and Vaccine Preventable Diseases Surveillance. It identified data quality issues at all administrative level, such as coverage above 100% at local levels and lacking of data triangulation indicate high possibility of inaccuracy of administrative coverage. Even though the Ministry of Health has been conducting several activities to improve quality of immunization data by regular data quality self- assessment, biweekly desk review and roll out of electronic immunization registry, the challenges remain. Another data source to monitor immunization coverage is surveys. Vaccination coverage survey can assist to monitor immunization coverage in complement with administrative coverage. It also provides analysis on contributing factors of immunization performance and verify administrative data report. Latest vaccination coverage survey was in 2023 covering under five immunization program. Therefore, it is important to conduct this vaccination coverage survey for routine and new vaccines program that includes school-age and women of reproductive age immunization and behavioral and social drivers of immunization. |
| Objectives | - To assess the vaccination coverage rates of routine immunization and new vaccines program across different regions of Indonesia, identify any gaps in coverage, and understand factors influencing vaccine uptake. Specific objectives: - To assess coverage rates of specific antigens and fully immunized status of infants, 2nd years of life, school age immunization, Tetanus Toxoid Containing Vaccine (TTCV) immunization of women of reproductive age - To monitor immunization program performance, routine and new vaccines, at national and subnational level, based on antigens, age, gender, socioeconomic status and disability - To measure the coverage of vaccines recently introduced into the national immunization programme and compare this to routine immunization coverage |
| Study Methods | The VCS is a quantitative study that follows the guidelines outlined in the World Health Organization's Vaccination Coverage Cluster Surveys: Reference Manual and Behavioral and Social Drivers of Vaccination: Tools and Practical Guidance for Achieving High Uptake. A multi-stage cluster sampling methodology, adapted from the standardized method recommended by the WHO, will be employed. In the first stage of sampling, one district per province will be randomly selected to represent the population. Secondly, 39 clusters (sub-district and village) will be randomly selected from each district. Last sampling is to select 83 households randomly that will be visited from each cluster. A total of 22,192 respondents is expected to participate in the survey with target population includes all children age of 12–23 months old, 24–59 months old, women who gave birth or experienced miscarriage in the last 12 months, and girls age of 12–15 years old. The data for the cluster selection is provided by Statistics Indonesia (BPS) which has a list of enumeration areas and their population. This survey will utilize quantitative data collection methods, combining household interviews with the verification of vaccination cards or home-based records. Data will be collected both electronically and manually, followed by data cleaning. Data analysis will be performed using IBM's SPSS Statistics software suite, and vaccination coverage rates will be calculated for each vaccine and demographic groups. |
| Expected outcomes and use of results | The main outcome to be analyzed is the routine immunization and new vaccine vaccination coverage rates for children aged 12 – 23 months, 24 – 59 months, girls 12 – 15 years old and for women who gave birth or experienced miscarriage in the last 12 months. Results will be stratified by sex, age group and region (urban/rural area). Secondary outcomes include reasons for not vaccinating.

Results will be stratified by sex, age group and region (urban/rural area). Secondary outcomes include reasons for not vaccinating. |
