Many people scared of needles even if they only see it, especially if the needle had been injected. Fortunately, scientists have realized this and developed micro-sized needles so tiny you will not be felt in the skin.
This micro needle shaped like a tape so it is very practical. Self-taped to the skin and then a very small needle into the skin and release the vaccine. In the future, these micro-needles can be used alone even at home.
In a trial of micro syringes without a vaccine, almost all participants said that these needles did not hurt. Needle length is about 650 microns (three percent inch). “Plaster needle” is simply taped to the skin and set aside for 5-15 minutes. In experiments on rats, “plaster needle” delivers accurate doses of the vaccine as well as ordinary needle method.
The medical world has long been using stickers (patches), such as the nicotine patch for people who want to quit smoking. This method makes the drug more easily absorbed the content of the skin. However, the method for flu vaccine patch is absorbed into the skin has so far not succeeded.
In the recent innovations undertaken by a team from the Georgia Institute of Technology, the vaccine was given via a needle. But the size of the needle is very small so it will not hurt and does not need special training to use them. So people will not be afraid anymore and do not need no needle waste.
“Our goal is to create a vaccine-friendly method for patients. It means not to cause fear but patients can also use it alone,” said Mark R. Prausnitz of Georgia Tech.
