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.
A lot slower, though. Article says it takes a minute and a half.
It takes my kid half an hour of screaming and throwing a public fit just to get within two miles of a needle, so I’ll take it.
Fair enough.
Also consider the people who have needle phobias. My heart starts to race before getting a vaccine. If I have to give a blood sample I will faint.
I’m getting woozy talking about this.
