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.

Neat. I wonder if my grandchildren will see that technology in use, because I doubt it'll happen in my lifetime.

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.

That does sound amazing. Do we know if they lose any effectiveness?

Notwithstanding but I read about this, or something similar to this years ago, I want to say something seven or eight, and we're still in the same phase with this tech.

Not going to be holding my breath on this one.

The mRNA shots are very sensitive. I'm not allowed to shake them prior to administration, only swirl gently. I feel like this tech will damage them no?
