What are Immunization Information Systems (IIS)?

By two years of age, over 20% of the children in the U.S. typically have seen more than one healthcare provider, resulting in scattered paper medical records. Immunization information systems (IIS) help providers and families by consolidating immunization information into one reliable source. They also save money by ensuring that children get only the vaccines they need and improve office efficiency by reducing the time needed to gather and review immunization records.
