The National Immunization Survey (NIS), sponsored by the Centers for Disease Control and Prevention, is currently a random-digit-dial telephone survey that monitors child immunization levels. Parents in the eligible households complete an interview, and provide their child’s immunization history and permission to contact the child’s medical provider to verify the child’s immunization records.

The U.S. Census Bureau is conducting an Evaluation Study to test the possibility of conducting the NIS using the American Community Survey as the sampling frame. Because this Evaluation Study will use a Census Bureau sampling frame, it must be conducted under the Census Bureau’s Title 13 requirements. Providers must receive Special Sworn Status before they can provide the child’s detailed immunization history. The procedures for obtaining Special Sworn Stat us from the health care providers add an extra step to the NIS data collection process.
