The National Immunization Surveys (NIS) are a group of telephone surveys sponsored and conducted by CDC’s National Center for Immunization and Respiratory Diseases (NCIRD). Since 2018 the National Immunization Surveys have used a single frame survey design, that includes calling cell phone numbers for household interviews with parents or guardians. If the parent or guardian provides consent and contact information, a questionnaire is mailed to children’s vaccination providers. Learn more…
