CDC reports 216 child deaths this flu season, the most in 15 years

The flu vaccination rate for U.S. children has plummeted from about 64% five years ago to 49% this season.

“This number that we have now is almost certainly an undercount, and one that — when the season is declared over, and they compile all the data — it’s almost certain to go up,” said Dr. Sean O’Leary of the American Academy of Pediatrics.
