Parents are key decision-makers and promote complete immunization programs. Health education for parents enhances knowledge, practice, and shifts negative perceptions. Aim: This study aimed to design a health education program about childhood obligatory vaccines. Method: The Delphi technique is used to design the program. Judgmental sampling technique was used to recruit 10 health educators, 10 experts in health education, community health programs, communicable diseases, and community health nursing, and purposive sampling technique was used to recruit 16 mothers of vaccinated children. Results: Participants provided highly positive feedback on the health education program. They strongly agreed that the program enhanced their understanding of childhood obligatory vaccines. The objectives and learning materials were rated favorably, with participants highlighting that the program addressed various learning styles effectively. Conclusion: This study highlights that a well-designed health education program on childhood obligatory vaccines helps mothers better understand the importance of timely immunization. By providing clear, practical, and accessible information, the program addresses common concerns, corrects misconceptions, and empowers mothers to make informed decisions that protect their children's health and contribute to community well-being.
