Doctors say that vaccinating all children can help combat the spread of influenza to the general population

An advisory panel for a U.S. government health agency recommends greatly increasing the number of American children who receive the influenza immunization each year. The panel suggests every child from age six months to 18 years receive a flu shot.   The new guideline would expand by some 30 million the number of young people who should be vaccinated.  Leta Hong Fincher has more.
