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.

This is more unsettling than a needle to me.

What do you think about jet injectors?

a narrow, high-pressure stream of liquid penetrates the outermost layer of the skin to deliver medication to targeted underlying tissues

It's how I got some vaccines in gradeschool. To the underside of my upper arm, the fatty bit. Hurt like fuck.
