There are multiple institutions and providers involved in providing vaccination information for infants and toddlers, including obstetrics, pediatrics, public health centers, obstetricians, pediatricians, internists, midwives, public health nurses, and nurses. However, in the absence of systematic vaccination education for providers, differences in recognition and information quantity exist due to variations in affiliated institutions, professions, and positions. In reality, vaccination education is often left to the discretion of individual healthcare workers, resulting in information disparities for vaccine recipients.

To ensure that all healthcare professionals involved in vaccinations share a unified understanding and can implement standardized vaccination education, it is essential to establish reliable educational materials and programs that can be commonly used across multiple disciplines.
