The flu season is getting worse, and U.S. health officials say it's partly because the flu vaccine doesn't protect against most of the spreading flu bugs. The flu shot is a good match for only about 40 percent of this year's flu viruses, officials at the U.S. Centers for Disease Control and Prevention said Friday.
The situation has even deteriorated since last week when the CDC said the vaccine was protective against roughly half the circulating strains. In good years, the vaccine can fend off 70 to 90 percent of flu bugs.
Infections from an unexpected strain have been booming, and now are the main agent behind most of the nation's lab-confirmed flu cases, said Dr. Joe Bresee, the CDC's chief of influenza epidemiology.
It's too soon to know whether this will prove to be a bad flu season overall, but it's fair to say a lot of people are suffering at the moment. "Every area of the country is experiencing lots of flu right now," Bresee said.
This week, 44 states reported widespread flu activity, up from 31 last week. The number children who have died from the flu has risen to 10 since the flu season's official Sept. 30 start.
Those numbers aren't considered alarming. Early February is the time of year when flu cases tend to peak. The 10 pediatric deaths, though tragic, are about the same number as was reported at this time in the last two flu seasons, Bresee said.
The biggest surprise has been how poorly the vaccine has performed.
