Flu vaccination: Win some, lose some
If you got the flu shot last year and it didn't work, don't reject vaccination.
During last year's battle of The People vs. Influenza, the virus gained the upper hand. Early in the 2014–15 flu season, a new strain of the virus emerged against which the existing vaccine offered virtually no protection. Hospitalizations for flu in older adults spiked to the highest level in a decade.
