Ind. (WHAS11) -- Flu-related deaths in Indiana have risen from 58 to 61 this week. State health officials now say this season's flu vaccine is less effective than originally thought.
Officials say the vaccine has a 56 percent overall effectiveness rate for children and adults up to age 64. In those 65-years-old and older, the vaccine is only nine percent effective.
Despite the reports, the state health commissioner still says the flue vaccine is the best method for preventing the flu.
