Nebraska Health and Human Services System
“The state of Nebraska conducts annual surveys of influenza activity in the state. There are multiple tools in place to collect and report data about health status related to influenza activity.
“During the current vaccine shortage and the shortage that occurred last year, the state of Nebraska used the Health Alert Network to communicate with providers and public health departments. Various automated surveys, fax surveys, and phone calls helped determine vaccine supply, antiviral supply, and vaccine need across the state. Many of these data sources were integrated into GIS and printed as maps for public health communication purposes and for data analysis by public health professionals.
“The map shows the number of doses of flu vaccine interpolated by the population by health district. The product is the number of doses per resident.”
