The researchers also found that a sub-group of mice, who were given only one dose of vaccine containing an additional substance called an adjuvant used to spur immune response, вЂњdidnвЂ™t get sick at all,вЂќ said Muller. The immune systems of those who got the patch produced high levels of neutralizing antibodies after two doses, including in their lungs, vital to stopping Covid, and the patches outperformed syringes. Mice were injected either via the patch over the course of two minutes, or with a syringe. The researchers used a so-called вЂњsubunitвЂќ vaccine that reproduces the spikes that dot the surface of the coronavirus. вЂњItвЂ™s like you get a good flick on the skin,вЂќ said Muller. These tips have been coated with an experimental vaccine, and the patch is clicked on with an applicator that resembles a hockey puck. The Australian-US team used patches measuring one square centimeter that were dotted with more than 5,000 microscopic spikes, вЂњso tiny you canвЂ™t actually see them,вЂќ David Muller, a virologist at the University of Queensland and co-author of the paper, told AFP.

The technique could help save childrenвЂ™s tears at doctorsвЂ™ offices, and help people who have a phobia of syringes.Д«eyond that, skin patches could assist with distribution efforts, because they donвЂ™t have cold-chain requirements - and might even heighten vaccine efficacy.ДЄ new mouse study in the area, published in the journal Science Advances, showed promising results. Effective vaccines, without a needle: Since the start of the Covid pandemic, researchers have doubled down on efforts to create patches that deliver life-saving drugs painlessly to the skin, a development that could revolutionize medicine.
