Ultrasound can push vaccines into the body without needles
Vaccinations could be made less painful by treating skin with a vaccine-laden liquid and using ultrasound to push it into the body
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 guess it's interesting but this seems to have minimal use case. For those with reactions to injections and such it's useful, but it seems much easier to use a needle in most cases. Also that article claims that it "doesn't damage the skin", but I don't see why a vaccine would cause any meaningful damage to the skin in the first place.
Edit: Okay I'm seeing now how this would be useful for more frequent injections like insulin and such if it can be used like that.
It literally tears a hole in the flesh with a puncture wound. It's the definition of damaging.
Minor damage, but damage none the less.
I have a phobia of needles so this comes in very very handy. I just wish there was one for taking blood out.

I guess the fear of needles is a constant problem when children are vaccinated. Having an alternative method ready could make it easier for children, parents and doctors.
Not only children. I know a guy that passes out (or almost does) when they try to inject him with needles.
I know a guy like that too. Okay, it’s me. I have to ask the doctor to let me be lying down when I get a shot. But at least it’s not as embarrassing as passing out in the little chair and have a 115 lb. nurse trying to hold me up before I hit the floor. That has happened more than once.
