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.

I had a friend who would have severe reactions to injections. He wasn't afraid of needles, but his body would have weird reactions lasting about a week after having an injection. It was really problematic, so he tried to avoid them whenever possible. All this to say, I bet he'd be excited if something like this were made available to him.

Had a class mate in elementary school that literally ram screeming when we were getting out hepititis shots. This would be great for someone's like that who is very much afraid of needles
