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.

Someone being a vegan doesn't exactly put other people at risk.

Where does other peoples' freedom start? Do you also have the freedom to burn toxic materials in your backyard, where your neighbours can inhale the smoke? Because proper disposal of toxic waste is much more similar to getting vaccinated than your metaphor.
