In the 50 states and 6 cities that operate registries regionally or state-wide, an average of 76% of public immunization provider sites submitted data to their IIS during the last six months of 2003. Twenty states and four cities reported over 95% of their public immunization provider sites submitting data to the IIS. These results are based on self reported data from CDC immunization grantees.

MA and MD provider participations are not reported. Within each state, only Boston and Baltimore City reported rates. The rates were too small to reflect an accurate picture of provider participation in each state.

Qualifier: reported annual fluctuations in public provider participation may be due to programmatic and/or technical changes to the immunization information system.
