National Immunization Surveys

National Immunization Surveys (NIS) are research efforts conducted in the United States to assess vaccination coverage among children and adolescents. These surveys gather data on vaccination rates by contacting families and healthcare providers, ensuring a representative sample across different regions and demographics. The information collected helps public health officials understand immunization trends, identify areas of low vaccination rates, and develop strategies to improve public health. NIS plays a crucial role in monitoring progress towards vaccination goals and ensuring communities are protected from vaccine-preventable diseases.
