This Year's Flu Shot Is Just 36% Effective

It goes without saying that the flu has hit the United States hard this year, and the worst weeks may be yet to come.

The Centers for Disease Control and Prevention just released a statement that this season's flu shot is 36 percent effective — better than doctors anticipated, but still not a great number.

This is shaping up to be the worst influenza season in recent years, and it might still get worse before it gets better, according to the CDC. The flu season frequently extends into May, and it’s only the middle of February.
