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.

That does sound amazing. Do we know if they lose any effectiveness?

Probably not, theres been some needleless vaccines before that did ok. If anyone has done time in the military you're probably familiar. Also any loss in efficacy could probably just be offset with higher concentrations

First of all, thank you for taking the time help me understand. I didn't know about past vaccines that used the system.

[–] tinwhiskers@lemmy.world 1 points 11 months ago

They didn't use this system. There are other needleless systems, primarily jet systems that use high pressure.

The smallpox vaccine was put on a sugar lump that children then ate (It really was a different time) And even after going through the digestive tract it still worked.
