Many a child has been temporarily traumatized by the sight of a shot when vaccine time arrives, and although products like FluMist are safe for adults, kids are still subject to those flu shots when the time comes.

A better, under-the-tongue alternative may be coming your way soon, though. Korean research on mice has determined that a flu vaccine administered under the tongue worked great without the need for a needle prick (and accompanying emotional torture for many kids).

Will most vaccines be delivered without breaking the skin in the near future? It seems that there are always drawbacks to non-shot vaccines, but anything in medicine should be possible now that the human genome has been decoded.
