CDC’s Countermeasure and Response Administration System for Monitoring H1N1 Vaccine Doses Administered

The National Strategy for Pandemic Influenza: Implementation Plan, released in November 2005, calls for monitoring the appropriate usage of pandemic influenza vaccine.1 To accomplish this, Public Health Emergency Preparedness Grantees or Project Areas (which include the 50 states, District of Columbia, New York City, Chicago, Los Angeles County, and 8 US territories and freely associated states) are expected to track pandemic influenza vaccine doses administered at the individual patient level and send a subset of data on a weekly basis to the Centers for Disease Control and Prevention (CDC). CDC has created the Countermeasure and Response Administration (CRA) system, a computer-based informatics application, to help Project Areas track medical and nonmedical countermeasures used during a public health emergency or event, including pandemic influenza.2
