NEW YORK (AP) — More U.S. children have died this flu season than at any time since the swine flu pandemic 15 years ago, according to a federal report released Friday. The 216 pediatric deaths reported by the Centers for Disease Control and Prevention eclipse the 207 reported last year. It’s the most since the 2009-2010 H1N1 global flu pandemic.

The pediatric death toll from the flu this season is the highest it’s been since the 2009-2010 swine flu pandemic, according to a new report from the Centers for Disease Control and Prevention (CDC).

Plummeting vaccination rates have contributed to 216 child flu deaths, the highest number since the swine flu pandemic.
