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.

    If humans weren’t meant to stabbed then we wouldn’t be so soft and penetrable.

    I do take your point though.

      Lol, it’s true. But if we were meant to be stabbed we wouldn’t have a completely unique dangerous (occasionally it kills people) reaction to it that doesn’t resemble most phobias.
