A research team from the Australian University of Queensland has developed a new vaccination method against the corona virus. With the help of a special plaster, vaccinations could soon be completely dispensed with by syringes.

Scientists from Australia’s University of Queensland, together with the Brisbane biotechnology company Vaxxas, have developed a new vaccination method using a patch. The experiments with mice show that the patches were probably more effective against the corona virus than an injection with a syringe.

New corona vaccination method: patches significantly more effective than injections

Study author Christopher McMillan puts this down to a simple reason, as he told Science Daily: “The high-density microarray patch is a vaccine delivery platform that delivers the vaccine precisely to the layers of the skin that are rich in immune cells.”

He went on to say that this made the patch 11 times more effective at fighting the omicron variant than the same vaccine injected with a needle. The HexaPro vaccine was initially tested. Other vaccines were then tested and the patch always produced a better immune response.

Simple application and uncomplicated transport

The researchers conclude from their study that their patch method “could represent a promising addition to current SARS-CoV-2 vaccine approaches”. In addition, the simple application and uncomplicated transport would help to provide vaccinations, especially in resource-poor areas.
