A study just released says that this winter's flu vaccine is only 23% effective. That, however, is not the even the worst percentage in the past ten years.

In the past ten years flu vaccine effectiveness has ranged anywhere from 10% to 60%, according to yahoo.com. This year's percentage does have officials at the CDC concerned enough to urge doctors to increase the use of antiviral medication for patients who get the flu.

There are several reason for the lower level of effectiveness, including several strains of the H3N2 virus that are making their way around that aren't covered in the vaccine. And according to yahoo.com, the effectiveness in those between 18 and 49 years old was just 12 percent.

Despite the findings, The CDC is recommending get the flu shot if they haven't already, saying it could prevent severe infections that could result in hospitalization or death.

In addition to getting the vaccine, the CDC also suggests some everyday things you can do to lower your chances of getting the flu. Wash your hands often, and if soap and water aren't available, use an alcohol based hand rub. You should also clean and disinfect surfaces and items that may be contaminated with germs.
