UNITED STATES - The CDC has confirmed the nasal flu vaccine is less effective than the shot among children in recent flu seasons.
Experts did not recommend Flu-mist during the past two flu seasons because of concerns that it offered less protection.
Now, data from 2013 to 2016 shows Flu-mist was only 20 percent effective against Influenza-A and H1N1.
The flu shot was 67 percent effective. Still, the American Academy of Pediatrics does recommend the flu shot as the best choice for children.
