Sticky patch with vaccine-infused microneedles prompted immune response

DIY vaccination may be on its way. In the first test in adults, a Band-Aid‒like patch studded with dissolving microneedles safely and effectively delivered a dose of influenza vaccine.
People using the patch had a similar immune response to the flu vaccine as those who received a typical flu shot, researchers report online June 27 in the Lancet. And nearly all of the patch users described the experience as painless.
The patch eliminates the need for safe needle disposal, and since it is stable at room temperature for at least a year, it doesn’t require refrigeration, unlike other vaccines. So, it could eventually end up on pharmacy shelves, making vaccination more akin to picking up aspirin than visiting a doctor. Along with possibly improving vaccination rates in the United States, the patch could make delivering vaccines in developing countries
