National Immunization Survey

The National Immunization Survey (NIS) is a large-scale effort by health officials to collect information about childhood vaccination rates across the United States. It involves contacting households and healthcare providers to gather data on which vaccines children have received. The purpose is to monitor immunization coverage, identify areas needing improvement, and ensure children are protected against preventable diseases. The survey helps public health agencies make informed decisions and develop programs to increase vaccination rates, ultimately aiming to improve community health and prevent outbreaks of vaccine-preventable illnesses.
