The goal of this observational study is to learn about vaccinations hesitancy, delay or avoidance in children with chronic diseases, congenital anomalies or disabilities. The main questions it aims to answer are:
• Attitudes of caregivers towards vaccinating their children, obstacles that postpone vaccinations, and the status of vaccinations of these children.
Participants will fill out questionnaires and some will be included in focused groups for the qualitative part of the study.
Researchers will compare the vaccinations status of the research group to their siblings' status as well as the published national records of vaccination compliance.
