Not a fan of needles? You are not alone. According to this new TED talk by biomedical engineer Mark Kendall, roughly 20 percent of the population is 'needle-phobic.' These are folks that don't just dislike shots, they actively go out of their way to avoid any kind of vaccine or medication given by injection.
Regardless of your stance on vaccines, I think we can all agree that their current method of delivery leaves much to be desired. And no wonder - as Kendall explains, the needle-and-syringe method for giving people shots is almost 160 years old. Surely, someone could have come up with a better way in all that time, right?
It seems they finally have. A one-centimeter-by-one-centimeter square patch that can be applied painlessly to the skin. It's also easier to transport and safer to use than its pointy predecessor. Oh, and it's cheaper, too.
Are needle-free nano-patches the wave of the future for vaccines? Check out Kendall's TED talk and see what you think:
