CDC confirms: FluMist nasal spray is less effective than the shot

NBC - The CDC has confirmed the nasal flu vaccine was less effective than the shot among children in recent flu seasons.

Experts did not recommend FluMist during the past two flu seasons because of concerns that it offered less protection against H1N1

Now data from 2013 to 2016 shows FluMist was only 20 percent effective against Influenza A and H1N1.

The flu shot was 67-percent effective.

The CDC voted to bring back FluMist this season after it was reformulated.

Still, The American Academy of Pediatrics recommends the flu shot as the best choice for children.
