Scientists have developed an influenza vaccine delivered by a micro-needle patch that patients could easily and painlessly take themselves. This would be awesome because then you do not have to get a shot for your influenza vaccine anymore. The patch basically dissolves into your skin, instead of getting the shot. The scientist have tested it on mice, and it has been proven to work 100% effective more than a year after the mice were vaccinated.
The influenza vaccine uses dry virus-like particles (VLP) instead of a liquid with the dead or attenuated virus. The VLPs coat the micro-needle patch with a stabilizing agent, so the patch wouldn't need to be refrigerated. Using this needle will reduce the already low risk of side effects and also the needle is only seven-tenths of a millimeter in length. The VLP-coated micro-needles actually provide greater protection than the intramuscular immunization. After testing it on the mice, they have received the numbers, and you just can't beat those number after 14 months the mice were still 100% protected. One researcher at Georgia State said "he envisions patients some day being able to self-administer the vaccine easily and painlessly and with fewer side effect she envisions patients some day being able to self-administer the vaccine easily and painlessly and with fewer side effects." With this being said, this seems like a good new discovery for people who don't like needles and not a fan of pain.
