Estimated Influenza Vaccination Coverage Among Adults and Children—United States, September 1, 2004–January 31, 2005

A report on the estimated influenza vaccination coverage among adults and children in the US during Sept 1, 2004- Jan 31, 2005 indicates that influenza vaccination coverage levels in priority groups nearly reached those in recent years, whereas coverage levels among adults not in priority groups were approximately half of levels in 2003. The results further suggested that designation of the priority groups successfully directed the nation's influenza vaccine supply to those at highest risk. A CDC editorial note is included.
