Needle-free flu vaccine? Not so fast!

On second thought. Maybe the hypospray did hurt?

Bummer.  We were getting so close to the Star Trek reality we always dreamed about.  We can now talk to our communicator-like, Siri-enabled iPhones and until this week, we could get a flu vaccine using a hypospray-like needle-less jet injector. Unfortunately, for your deltoids, FDA now recommends against the use of the intramuscular-labeled vaccine using jet injectors.  Only one vaccine, the MMR, is approved for use with the jet injector and the FDA hasn't received the safety and effectiveness data to approve other vaccines using this technology.

Note: This does not apply to the intradermal vaccine, which is supplied in its own pre-filled syringe.
