Soon flu shot could be easy sticking on a Band-Aid. The DIY vaccination on its way and in its first test, Band-Aid patch dotted with softening microneedles safely as well as it efficiently carried a dose of influenza vaccine. The researcher stated that the people using the patch had a similar immune response to the flu vaccine, also people sharing their experience of using patch was painless. The latest patch does not require safe needle disposal and at room temperature, it is stable for one year. Dissimilar to the other vaccines the patch doesn’t require refrigeration, so it could ultimately end up on pharmacy shelves.
The researcher said that the patch could make delivering vaccines in developing countries easier. A vaccinologist at the University of Maryland School of Medicine in Baltimore, Myron Levine noted that more part of patch remains with the testing. Myron Levine said, “what a great first start”. Further, Levine added, “I love the idea of not having to worry about a needle and syringe”.
The patch has two sides, one side of the patch looks like a bandage and the other side of the patch consists of an array of 100 hard cone-shaped microneedles, each microneedle little more than half a millimeter tall. It is made of sugar, vaccine and polyvinyl alcohol. A study co-author and chemical engineer at the Georgia Institute of Technology in Atlanta, Mr. Mark Prausnitz said, “Having the patch on feels a little like Velcro being pressed against the skin”. The microneedles enter the outer layer of the skin and run when it strapped into the back of the wrist. Mark Prausnitz said, “Testing in people of a patch with polio vaccine is planned, in order to aid polio eradication efforts”.
