UNDATED - Preliminary results are now in from the government's test of the swine flu vaccine for children.
Health officials say some kids may need just one shot of the new vaccine.
Early results show most children ages 10 and older had robust immune response to the low dose of the vaccine.
That means just one shot for most kids older than 10, but younger children may need two. Scientists won't know for sure how many shots will be needed for a few weeks.
