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 don't think there would be any need to dispose of any part of the ultrasound system; perhaps a disposable paper or plastic cover to speed up cleaning between patients. Meanwhile the needles are single use and must be disposed of properly since they are a bio-hazard. Can't really see how a needle could possibly compete on the waste side of things.

Yeah, maybe he was talking about something else because it's hard to see what would be worse than used needles.
