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.

Forced vaccinations weren't and still aren't a thing in the US. (I'm sure there were exceptions, but I mean large scale and general public)

However requiring a vaccine in order to participate in society (jobs, school, etc.) is perfectly reasonable. It's still a choice, just that the consequences are on those making the choice instead of on those around them.
