0:11 It 's a pleasure to be here in Edinburgh, Scotland, the birthplace of the needle and syringe. Less than a mile from here in this direction, in 1853 a Scotsman filed his very first patent on the needle and syringe. His name was Alexander Wood, and it was at the Royal College of Physicians. This is the patent. What blows my mind when I look at it even today is that it looks almost identical to the needle in use today. Yet, it 's 160 years old.

So let 's start with the obvious: Many of us don 't like the needle and syringe. I share that view. However, 20 percent of the population have a thing called needle phobia. That 's more than disliking the needle; that is actively avoiding being vaccinated because of needle phobia. And that 's problematic in terms of the rollout of …show more content…
The tiny projections are covered in a dry vaccine powder to deliver a small dose of vaccine. These projections penetrate past the dead skin cells and into the immune cells that lay directly beneath the skin cells. The Nanopatch is easily applied using an applicator, immunising a person in about a minute and is then safely disposed of once removed. It is made for less than $1 as it uses only a fraction of a vaccine dose delivered by traditional syringe methods. The process does not draw blood, reducing the risk of infection and at the same time eliminates the risk of needle stick injuries. As the Nanopatch does not contain liquid vaccine but dry vaccine, it is not required to be refrigerated and therefore is transported with ease.
How vaccines work:
Vaccines introduce the body to an antigen – a safe form of a germ. The antigen tricks the body into mounting an immune response, learning and remembering how to deal with intruders. When the body is subjected to the real intruder, the body quickly mounts an immune response to deal with that vaccine, and neutralises the infection.
Short comings of using traditional needle and syringe to deliver vaccines:
1. Pain – 20% of the population have needle-phobia. People deliberately avoid getting injections and vaccines due to their
