Needle Free Vaccination

How good would this be? According to a recent TED talk by Mark Kendall it could soon become reality (http://www.ted.com/talks/mark_kendall_demo_a_needle_free_vaccine_patch_that_s_safer_and_way_cheaper.html).

Instead of using a needle and syringe the vaccine is applied via a patch that is placed on the skin. The patch contains thousands of projections that release the vaccine into the top layers of the skin. As well as being pain free the administration of the vaccine into the skin, rather than the muscle, also generates a more powerful immune response. This means that much less vaccine is required (up to one hundredth of the traditional dose) lowering the cost and decreasing the possibility of undesirable side effects.

The vaccine that coats the patch is in a dry form. Therefore, it does not need to be refrigerated, unlike traditional vaccines, and will retain its potency at 23 C for up to a year. This makes it much more feasible to use in countries where electricity and refrigeration are difficult to guarantee, such as Papua New Guinea which has only 800 refrigerators. Patch trials are due to start there soon.
