Adding to the coolest inventions of 2012

Or at least to my personal list: The new flu vaccine.

Some smart person working for a pharmaceutical company came up with an intradermal flu vaccine.

The nice thing is that you can't see the needle coming. It honestly looks like a hypospray, although it does still prick a little bit. And for the first time EVER the arm I got the shot in isn't aching afterwards. (Some people do still report muscle aches). They do say there's a slightly higher risk of swelling or itching at the injection site.

The other really cool thing is that the new vaccine requires 40% less of the active ingredient than the normal shot. Which means you can make more of it...and given issues in the past with flu vaccine shortages.

Besides.

It really is the closest thing to a hypospray yet.
