This terrible flu season: What you need to know

The current flu season is particularly deadly due to the specific virus strains combined with a "fluke" that rendered this year's vaccine less effective than desired, Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, tells Axios. The Centers for Disease Control and Prevention today announced interim results of the vaccine's overall effectiveness, which is 36%.

Why this matters: Healthy individuals are being struck down by the flu this season and some communities have taken steps like shutting schools to combat the contagion, which has killed at least 63 kids in the U.S. since the start of this flu season in the fall. While the CDC will update its influenza data soon, authorities say early indications do not show a slowdown yet.
