Ultrasound can push vaccines into the body without needles (www.newscientist.com)

Vaccines can be delivered through the skin using ultrasound. This method doesn’t damage the skin and eliminates the need for painful needles. To create a needle-free vaccine, Darcy Dunn-Lawless at the University of Oxford and his colleagues mixed vaccine molecules with tiny, cup-shaped proteins. They then applied liquid mixture to the skin of mice and exposed it to ultrasound – like that used for sonograms – for about a minute and a half.

If humans weren't meant to stabbed then we wouldn't be so soft and penetrable.

I do take your point though.

Lol, it's true. But if we were meant to be stabbed we wouldn't have a completely unique dangerous (occasionally it kills people) reaction to it that doesn't resemble most phobias.
