Childhood Immunization Coverage

The National Immunization Surveys (NIS) are a group of phone surveys used to monitor vaccination coverage among children 19-35 months and teens 13-17 years. The surveys are sponsored and conducted by the National Center for Immunization and Respiratory Diseases (NCIRD) of CDC and authorized by the Public Health Service Act [Sections 306].
