Many people are scared when they see the syringe. Especially the children start crying. Some adults do not want to be vaccinated for fear of needle puncture. With all these people in mind, researchers are conducting research on corona vaccine without syringes and needles. They say such a vaccine could be given soon. News AFP.

Researchers say that a small bandage (patches) like medicine will be applied to the skin. This will be as effective as the vaccine in the body.

The new research was published in a report published in the journal Science Advances last Friday, local time. The report says that the results obtained by the researchers are promising.

The new vaccination strategy is expected to help alleviate fears of syringes as well as the vaccine delivery system. Because, in case of patches, cooling temperature will not be required for preservation of vaccine.

A team of scientists from Australia and the United States have jointly discovered these patches. The size of each patch is one square centimeter. It will have more than five thousand small spikes pierced. David Mueller, co-author of the research report and a virus specialist at the University of Queensland, said: “These are so small that you can’t really see them.”

The drug-coated patches will be placed on the skin using a small instrument. Mueller said the patches can cause skin rashes when applied. Researchers have experimented with rats on patches. Medicinal patches are applied to the body of some rats for two minutes. And some rats are vaccinated with syringes. It has been found that rats that have been vaccinated in two doses using patches have high levels of antibodies in their bodies.

Researcher Mueller added that the vaccine is primarily applied to our muscles, but does not have enough immune cells to respond to the drug. On the other hand, the skin of the area where the small spikes will be placed through the patches will die. And it will warn the body about the problem. And it will create a lot more immunity. The researchers said that dry-coated patches will stay good at a temperature of 25 degrees Celsius for at least 30 days. And at a temperature of 40 degrees it can be stored for a week. Researchers believe that it would be convenient to preserve these patches in developing countries. Mueller added, ‘It’s very easy to use. It will not require highly trained medical personnel to apply.

The patches used in this study were made by the Australian company Vaxus. Its experimental application to the human body is planned from next April. Two US companies, Micron Biomedical and Vaxes, are also competing to make patches. Among them, Vaxes is trying to make different types of patches with small needles. It will blend into the skin. They claim that if this is possible, the amount of spikes used in each patch can be reduced
