Vaccine patches are easier to administer and pain-free, but how do they fare when it comes to protection against COVID-19 ? Researchers from the University of Queensland in collaboration with a Brisbane biotechnology company have conducted a study on mice using skin patches as vaccines. They’ve revealed an 11 times greater efficacy of the user-friendly, needle-free vaccine patches in fighting Omicron and Delta variants as compared to traditional vaccines. The vaccine delivery platform consists of a high-density microarray patch that delivers the spike protein vaccine specifically into immune cell-rich skin layers.
