The reason why any vaccine needs to be given more than once (excepting the flu vaccine, which changes every year) is that researchers have found the each vaccination will only increase antibody levels by a certain percentage. Repeated "booster" shots increase this antibody production throughout adolescence to attain the optimal level of antibodies considered effective against that disease.

Yes. Children under ten who have an immature immune system need to take two doses of the vaccine to get the appropriate immune response that will enable them to be immunized against influenza.

In approximately three weeks after the second dose, full immunity should be established if the child is otherwise healthy with a fully functioning immune system.
