During the same period, the completeness of data for vaccine manufacturers and lot numbers in immunization systems also increased steadily, according to the CDC’s Morbidity and Mortality Weekly Report.
A major goal of the U.S. Department of Health and Human Service’s Healthy People 2020 program is to increase the portion of children under the age of six with immunization records in fully operational, population-based immunization information systems, or IIS, to 95 percent.
The 2011 ISS Annual Report showed that at least 84 percent of children in the United States under the age of six participated in IIS. In the study, participation was defined as having a record of at least two vaccinations. The increase from 2011 was two percent.
The CDC surveys 56 immunization programs every year in order to monitor the progress of IIS and their integration into national healthcare practices.
The HHS National Vaccine Advisory Committee recently published similar goals for IIS, including what core data elements should be required and what should be optional. Among the required are included vaccine manufacturer and vaccine lot number.
