Every spring, a distinguished panel consults with the World Health Organization to determine the composition of the annual flu vaccine; i.e., which strains of influenza will be targeted during the subsequent flu season (LINK).
It has become apparent that the 2014-15 flu shot is not as effective as it has been in the past… a “drift” or mutation of one of the strains has allowed many to take ill with the flu, even though they were vaccinated.
Regardless, the Centers for Disease Control and Prevention still recommends that people get their flu shot. The vaccine will help mitigate the impact of the mutated strain, and also protects against other strains of the virus.
The CDC also reminds everyone to seek medical attention if flu symptoms present themselves: fever, sore throat, cough and body aches. Antiviral medications can reduce symptoms and help keep patients out of the hospital.
