I hate injections and unfortunately have a history of passing out when I have had to have one. A new patch, however, could offer a vaccine without the need for a injection. The patch has been developed by the University of Queensland and tests on animals have shown it can be even more effective than a normal vaccination. It is the size of a 5p piece and contains thousands of tiny projections coated in the vaccine on the underside. Once applied to the skin these projections push through the outer layer of skin. The nanopatches need a fraction of the dose that would be needed for an conventional needle vaccination. They could also be safer, because they would avoid incidents of needle prick and cross contamination. They are also potentially cheaper to produce. All this sounds great, but for me the best part is that there are no needles involved, unfortunately they are not likely to available any time soon.
