NEW YORK — The flu vaccine may not be very effective this winter, according to U.S. health officials who worry this may lead to more serious illnesses and deaths.
Flu season has begun to ramp up, and officials say the vaccine does not protect well against the dominant strain seen most commonly so far this year. That strain tends to cause more deaths and hospitalizations, especially in the elderly.
“Though we cannot predict what will happen the rest of this flu season, it’s possible we may have a season that’s more severe than most,” said Dr. Tom Frieden, director of the Centers for Disease Control and Prevention, at a news conference Thursday.
CDC officials think the vaccine should provide some protection and still are urging people to get vaccinated. But it probably won’t be as good as if the vaccine strain was a match.
