Update 5:47 p.m. Jan. 8: A report in the Star Tribune says the Minnesota Department of Health has confirmed that a 14-year-old girl died, but did not include her name. 

According to the story, "Kris Ehresmann of the state Health Department confirmed that a girl of that age died and said that even if she had a flu shot, as some reports say, 'the vaccine is not 100 percent effective—so sadly, it is possible to have a situation in which someone vaccinated develops influenza.'

"In some cases, vaccination can modify disease, but that is not a guarantee," Ehresmann added. "We still are recommending vaccination" for everyone.

Before Tuesday, The Minnesota Department of Health reported four deaths in the state so far this flu season (as of Dec. 29, 2012). One of those who died was also a teenager: Max Schwolert, 17, of Texas, died Dec. 29 while hospitalized in St. Paul after becoming sick with the flu. He had been visiting relatives in Wisconsin, the Star Tribune reported.
