Needle-phobes welcome vaccine patch

Scientists say they've figured out how to vaccinate a person without using a needle, potentially giving the public one less excuse to avoid getting immunised.

Scientists say they've figured out how to vaccinate a person without using a needle, potentially giving the public one less excuse to avoid getting immunised.

The new technique, reported in the German journal Angewandte Chemie, relies on the use of a patch that administers the vaccine with the help of a special molecule.

While some people can take some vaccines orally, most have to be injected directly into a muscle.

Victor C. Yang, a researcher at the University of Michigan, and colleagues, developed a protein that can pass through the outer membranes of cells into the interior, carrying the vaccine with it.

The researchers noted that it may be possible for people to get booster vaccinations without needing to even visit a doctor. They may be able to use patches that they administer themselves.

If patients co-operate, this could make it easier to vaccinate people in poor areas of the world where it is difficult to get access to medical care. - (HealthDay News)
