Health officials brace for severe flu season

If you received a flu shot this year, it may not protect you from contracting the potentially deadly disease. Health officials say they are bracing for a severe flu season. In Australia, where the flu season is winding down, this year’s vaccine was only 10 percent effective. According to the Centers for Disease Control and Prevention, more than 7,000 flu cases have been confirmed in the U.S., which is more than double the number of cases at this time last year.
