The Centers for Disease Control says influenza has killed 105 children this year.
That's triple the number who died during last year's flu season. But flu deaths fluctuate a lot and it's not anywhere near the worst season for child deaths.
On Friday CDC officials released the report which highlighted that 90 percent of the children had not been vaccinated against the virus.
The CDC recently reported that the flu vaccine was not especially effective in those most at risk from flu, the elderly but it did protect children pretty well. This year a vaccinated child was 64 percent less likely to be hospitalized with flu or to need to see a doctor for symptoms.
Last year 34 U.S. children died from the flu. During the 2010-2011 flu season 122 children died and 282 children died between 2009-2010 during the H1N1 swine flu pandemic.
