Revolutionary Nanopatch Will Give People Vaccines Without Needles

Those who don't like vaccines can already be happy. Because  Australia’s Vaxxas, have created the Nanopatch.
This device is about as big as a dime and causes little to no pain when applied. The vaccine is coated onto thousands of pins that only penetrate the top layer of the skin. These vaccines according Vaxxas CEO David Hoey involve less cost and they take less time prepared before injecting to the skin. But it will be several more years of testing before the Nanopatch is available for use.

I think it's a scientific breakthrough. Because it has so less risks, for example as a needle-stick injury, as well as be less expensive to manufacture, and this will allow surely that the people don't have to pay much for them.
