Flu shot with smaller needle approved

SWIFTWATER, Pa. (AP) - The FDA has approved the first flu shot
injected with a tiny needle that sends the vaccine into skin rather
than muscle.
Sanofi Pasteur said Tuesday that the Food and Drug
Administration approved its Fluzone Intradermal vaccine for adults.
It will be available for the next flu season.
The new product uses a needle less than a tenth of an inch long,
attached to a pre-filled syringe that holds a smaller amount of
influenza vaccine than standard flu shots. The vaccine enters the
skin just below the surface, where there is a high concentration of
cells that are key to generating an immune response.
Sanofi says patients prefer shorter, slimmer needles to standard
ones, but there's no data yet on whether they hurt less.
