ATLANTA -- The Centers for Disease Control and Prevention says when it comes to people over the age of 65, this year's vaccine has a dismal 9 percent success rate combating this year's more prevalent strain of flu.

And overall, this year's flu vaccine has proved to be 50 to 65 percent effective, which is slightly below average compared to previous years.

"We simply don't understand totally why the elderly did not develop a really immune response to this vaccine. And that's something we're going to have to continue to look at and study more closely," CDC spokesman Tom Skinner said.
