Researchers developing a new method of vaccine delivery say soon people may get their annual flu shots in the mail.

Their method involves a patch with microneedles. They're so small they can't even be felt.

The tiny needles barely penetrate the skin before they dissolve and release their vaccine.

Researchers say the patch feels like fine sandpaper. Nearly ever test subject who received the microneedle vaccine say it was painless and easy.
