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.

History proves we do the cheapest, easiest, and fastest. So allow me to shit all over this idea...

This is slow at 1.5 mins vs a needle takes about 5 secs.
Takes skill to operate an ultrasound machine and probably training to get a consistent dose vs pull needle to this line and jab in arm to know you got it all in there.
Every Rite Aid and CVS would need an ultrasound machine vs here are these cheap disposable needles that require no power or maintenance.

Sure they might develop it faster or make a new more portable thing. But that's going to take a long long time when no one gives a shit to invest money in a new thing when needles work.

I'd like to be an optimist when it comes to things like this, some people really really can't stand needles and something like this would be great for them people. I hope it develops further.
