Hubungan Pengetahuan Ibu dengan Kelengkapan Status Imunisasi Dasar Usia 12-24 Bulan di Wilayah RW 13 Kp. Sapan Desa Sumbersari Ciparay Kabupaten Bandung

The high mortality and morbidity rates of infants in Indonesia remain a serious public health problem. One of the main causes of this condition is the emergence of infectious diseases that can actually be prevented through basic immunization. Diseases such as diphtheria, pertussis, tetanus, tuberculosis, poliomyelitis, measles, and hepatitis B are types of diseases that can be prevented by immunization, yet many children still have not received complete immunizations. This study was conducted to determine the relationship between maternal knowledge levels and the completeness of basic immunization status of children aged 12–24 months in RW 13 Kp. Sapan, Sumbersari Village. This study used a quantitative approach with a cross-sectional design and was conducted in August 2024. A total of 39 mothers with children aged 12–24 months became the study respondents through a total sampling technique. Data collection was carried out using a questionnaire, and the data obtained were analyzed using the Chi-square test. The results showed that the majority of mothers had a sufficient level of knowledge, namely 21 mothers (53.8%). In addition, the majority of toddlers, 28 children (71.85%), had received complete basic immunizations. The results of statistical analysis showed a significant relationship between maternal knowledge and the completeness of children's basic immunizations with a p value of 0.006 (p < 0.05). This indicates that the higher the mother's knowledge regarding the importance of immunization, the greater the likelihood of the child receiving complete basic immunizations. Therefore, it is important for mothers to continue to increase their knowledge about immunizations through various sources of information such as books, counseling, or consultations with health workers, so that efforts to prevent infectious diseases in children can be optimally achieved.
