Corona vaccine patch: Eleven times more effective than the injection?

They are said to be more effective against new corona variants than classic vaccinations: vaccination patches. Now Australian scientists have found this out.

The coronavirus pandemic is still a major global problem. Scientists continue to look for ways to stop the pandemic. For example, antibodies have recently been discovered that are said to work against all variants of the corona. It is also debated whether and for whom a fourth vaccination against the virus makes sense. Australian scientists, on the other hand, are working on a vaccination patch that should also protect against severe cases against the omicron variant.

Vaccination patches: Results of a study on the fight against corona

Scientists from the University of Queensland have published the results of a study on the patch vaccination method. It is attached to the skin and can penetrate the layers of the skin that are rich in immune cells. According to Christopher McMillan of the University of Queensland, the patch is therefore more effective against new variants of the corona than conventional vaccines.

“We found that patch vaccination was about 11 times more effective against the omicron variant than the same vaccine given by needle,” the researcher reported in the scientific journal. Science daily. So far, every patch-tested vaccine has produced better immune responses compared to traditional needle vaccination methods.

Vaccination patches are said to be more effective against new variants of corona

Dr David Muller of the University of Queensland goes loud Science daily to assume that currently available vaccines may not be as effective due to new corona variants constantly emerging. “This reduced efficiency was accentuated by the omicron variant, which contains more than 30 mutations in the spike protein,” Muller said. Due to the large number of mutations, the virus has the ability to evade the immune responses generated by current vaccines.

It’s different with the patch method. Patches are not only more effective against emerging variants, but also easier to manage. It is now necessary to expand production capacity and accelerate product development in preparation for large-scale studies. However, scientists also emphasize that current vaccination is still an effective means of fighting the pandemic.

5. Vaccination against the coronavirus – yes or no?

With the number of infections falling, the question is whether or for whom the 5th corona vaccination makes sense at all. Councils of politicians, authorities and the Permanent Vaccination Commission (Stiko) differ. The company Stiko, which is responsible for vaccination recommendations in Germany, recommends an additional, i.e. a fifth vaccination against the virus after the second revaccination for particularly vulnerable people – for example, very old people or people with immunodeficiency.
