What is a key benefit of the Immunization Information System?

The Immunization Information System (IIS) serves as a centralized database designed to track immunizations given to individuals within a specific jurisdiction. A key benefit of the IIS is that it ensures proper vaccine administration by maintaining accurate and up-to-date records of vaccinations. This information helps healthcare providers determine which vaccines a patient has already received, allows for appropriate scheduling of future doses, and ensures that vaccinations are administered according to recommended guidelines. By having access to a comprehensive immunization history, providers can avoid potential errors such as under-vaccination or over-vaccination, ultimately helping to enhance patient care and public health initiatives.

Other options do not align with the primary function of the IIS. It does not eliminate the need for healthcare professionals, nor is it focused solely on adult vaccinations, as it tracks vaccines for all age groups. Additionally, it does not reduce the number of vaccines needed; rather, it supports the appropriate delivery and management of vaccines already recommended for different populations.
