Single swine flu shot enough for older kids

Studies of the new swine flu vaccine show children 10 and older will need just one shot for protection against swine flu - but younger kids will need two.

The National Institutes of Health says that protection kicks in for older children within eight to 10 days, just like it does for adults.

But the preliminary data shows that younger children may need two shots 21 days apart - not a surprise, since the very young often need two doses of vaccine against regular winter flu the very first time they're immunized against that influenza version.
