The federal Centers for Disease Control says this year's flu season could be severe. That's because this year's flu vaccine doesn't match the dominant strain being found.
Maine Center for Disease Control and Prevention Director Dr. Sheila Pinette says flu vaccines are prepared the year before.
"Last year in mid-February, when they had come up with the preparation of the vaccine for this coming 2014-2015 season, the World Health Organization did not see a high circulation world-wide, actually, of the strain that we are presently using," Pinette says.
Pinette says it's still important to get this year's flu vaccine because it will provide cross-protection.
