Nationwide 30 children have died from the flu epidemic. Katharine Gallagher, 27, is another victim. Her death came with shocking speed after just a few days after first showing symptoms. It was later revealed that Gallagher had severe acute bronchial pneumonia, a complication of the virus. The Centers for Disease Control says even though a flu shot is not 100 percent effective, it can lessen someone’s chances of getting the virus by 10 to 60 percent.
