This season’s flu vaccine may do little to prevent infection with the main circulating virus strain because the strain has changed since the vaccine was developed, a new study suggests.
However, the vaccine is still likely to protect against severe illness and death, according to the U.S. researchers. They assessed the vaccine’s effectiveness against the H3N2 strain. The vaccine is also meant to protect against H1N1 and two strains of influenza B.
Lab tests suggest a “major mismatch” between the vaccine and the new, mutated version of H3N2, study leader Scott Hensley, a professor of microbiology at the University of Pennsylvania in Philadelphia, told CNN.
Another worthless vaccine! Where will it all end?
Its a crap shoot with well over a dozen strains they project will be in the US at any given year. Something is better than nothing when it helps get the body to fight when an infection happens.
