Nix The Needle And Prepare For The Patch

Researchers have developed an alternative to the dreaded needle. Instead of getting jabbed in the arm for a vaccination, a patch could be applied painlessly.  BBC reports:

The patch has hundreds of microscopic needles which dissolve into the skin. Tests in mice show the technology may even produce a better immune response than a conventional jab.

Writing in Nature Medicine, the team of researchers said the patch could one day enable people to vaccinate themselves.

Each patch, developed by researchers at Emory University and the Georgia Institute of Technology, contains 100 “microneedles” which are just 0.65mm in length. They are designed to penetrate the outer layers of skin, dissolving on contact. To test the technology, the researchers loaded the needles with an influenza vaccine.

One group of mice received the influenza vaccine using traditional hypodermic needles and another group were vaccinated with the patch. Patches that had no vaccine on them were applied to a third group of mice.

Three months down the line the team found the patch appeared to produce a more effective immune response in mice, then infected with the flu virus, than a standard vaccination.

If proven to be effective in further trials, the patch would mean an end to the need for medical training to deliver vaccines and turn vaccination into a painless procedure that people could do themselves. It could also simplify large-scale vaccination during a pandemic, the researchers said.

Although the study only looked at flu vaccine, it is hoped the technology could be useful for other immunisations and would not cost any more than using a needle.

“We envision people getting the patch in the mail or at a pharmacy and then self-administering it at home,” said Sean Sullivan, the study lead from Georgia Tech.

“Because the microneedles on the patch dissolve away into the skin, there would be no dangerous sharp needles left over.”

Co-author, Professor Richard Compans from Emory University Medical School, said the vaccine does not have to penetrate deeply because there are immune cells present just below the surface of the skin.

“We hope there could be some studies in humans within the next couple of years,” he said.

    Just what we need. This should take care of all those junkies that are afraid of needles.

      if a junkie can manage to make one of those i think he has every right to use it as he pleases.

        I guess you're right, but the junkies I was talking about would just steal them from the doctor.

    what a better way to inoculate the unwilling!

    More quackery from big pharma. If a flu vaccine is to work at all it must be inhaled into the lungs.

    But I’ll go with colloidal silver and marihuana, thanks all the same!
