Vaccine No Match Against Flu Bug That Popped Up Near End
ATLANTA (AP) – U.S. health officials say the flu vaccine has again turned out to be a big disappointment.
The vaccine didn’t work against a flu bug that popped up halfway through the flu season. Figures released Thursday show the vaccine was only 29% effective overall.
The Centers for Disease Control and Prevention says the vaccine turned out to be a mismatch against the later strain.
