Flu season is going to suck this year
Health officials are worried this year's flu season could be particularly severe.
'MURICA — The flu has arrived early in North America, as officials worry this season's outbreak could be severe.
According to the Center for Disease Control and Prevention (CDC), the percentage of patients reporting flu-like symptoms reached the 2.2 percent threshold by late November, indicating flu season had begun, USA Today reported.
Experts believe the U.S. could be hit hard by the H3N2 strain, the same strain behind Australia's especially bad flu season.
The flu vaccine has been shown to be 10 percent against H3N2, according to a research paper in Eurosurveillance.
Flu vaccines cause antibodies to develop in the body around two weeks after vaccination, according the the CDC.
These antibodies then help the body fight against virus infections that are in the vaccine.
The seasonal flu vaccine is designed to protect against influenza viruses researchers predict will be the most common during the upcoming season, the CDC reported.
