WASHINGTON - All U.S. children aged 6 months to 18 years should get a seasonal influenza vaccine every year, the U.S. Centers for Disease Control and Prevention said on Friday.

The CDC's Dr. Anne Schuchat said the agency was strengthening recommendations for children to get the vaccination against seasonal influenza, especially with fears that the new H1N1 virus will be added to the already expected burden of seasonal flu.
