One Targeted Strain Has Mutated
The Centers for Disease Control and Prevention has issued an advisory to American doctors that the current version of flu vaccine being used will be less effective than expected because one of the strains of the virus targeted by the vaccine has since mutated into a new form. The CDC continues to recommend getting the vaccination, because it will still provide protection against other strains of the virus, and can lessen the severity of the effects of the mutated strain. It also endorses the use of antiviral drugs such as Tamiflu and Relenza to limit complications for those who suffer severe flu symptoms. One silver lining: the latest CDC figures indicate that flu activity nationwide is lower than usual this year.
