SLOT XO Develop a vaccine patch pointed to be more effective than injection
On October 30, the AFP news agency reported that Researchers from the United States and Australia are now working to develop a practical vaccine patch. Based on the experimental data, the patch vaccine was more effective than the intramuscular vaccine. which also prevents injury from vaccination Longer shelf life than injectable vaccines And it's easier to transport because it doesn't require a refrigerator. If the vaccine patch can be created successfully It will be a major revolution in the medical field ever.
David Muller, a virologist at the University of Queensland and co-author of the study, said: A team of researchers from Australia and the United States created a 1 square centimeter patch. There are 5,000 tiny, almost imperceptible spikes and vaccine-coated patches on the patches.
in experiments with mice A 2-minute vaccination was performed and the patch was applied. It was found that the immune system of the mice using the vaccine patch It produces high levels of viral suppressing antibodies compared to two doses of vaccination, including pulmonary immunity, which is important in stopping coronavirus. And the patch is more effective than the injection. The researchers also found that the mice in the subgroup received a single-dose vaccine containing a substance used to induce an immune response. No symptoms of illness
The results indicated that The vaccine patch is more effective than the intramuscular injection because Muscle tissue has few immune cells. It also causes the skin to die locally. which will stimulate the body that there is a problem and stimulate the immune response better As for transportation, it's easier. because when the patch has been coated with the vaccine The vaccine on the patch will last at least 30 days at 25°C and 1 week in 40°C, which is only a few times longer than the Pfizer and Moderna vaccines at room temperature. hours only
