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.
Neat. I wonder if my grandchildren will see that technology in use, because I doubt it’ll happen in my lifetime.
They’re more likely to have “ports” installed. I mean, if people are already lining up to have chips put in their brains…
