I know it got me. Did it get you? Despite getting the flu vaccine last fall, I was down for the count with one of the nastiest bouts of flu I've ever had. According to US health officials, I wasn't alone. This flu season has been the worst in four years.According to the CDC, the flu vaccine was only 44% effective against the strains of the flu viruses that were out this year. While it gave 58% protection over the most predominant strain, it was completely ineffective against other types of the flu virus.
In previous years, the flu vaccine has had up to a 70% effectiveness. The vaccine is developed each year based on data about the currently circulating strains of the influenza virus. According to the CDC, the vaccine has been a good match to the circulating viruses in 16 of the past 20 years.
