This season’s flu vaccine is so far one of the most effective since the government began evaluating influenza vaccine performance in 2003, according to preliminary data from the Centers for Disease Control and Prevention. The vaccine was 59% effective overall, the CDC announced late Wednesday at an advisory committee meeting in Atlanta. The vaccine typically has an efficacy rate of 47% to 60%. Last year’s was just 23% because of a mutation in the virus’ dominant strain.
