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.
Was getting poke with a needle ever a problem that it needed this?
I know a person IRL that is morbidly afraid of needles, they would have a panic attack just seeing others getting poked. And apparently they have a self-help group somewhere, so they are definitely not alone.
Yeah, vaccine like these can definitely save their live.
