Immunization Information System (IIS)

An Immunization Information System (IIS) is a secure digital database that collects and maintains vaccination records for individuals within a community or region. It helps healthcare providers, public health officials, and patients track immunizations to ensure people receive the right vaccines at the right times. This system improves vaccination coverage, prevents missed doses, and supports public health efforts to control vaccine-preventable diseases. By centralizing vaccination data, IIS enhances healthcare coordination, reduces errors, and provides valuable insights for managing immunization programs effectively.
