Scientists around the world are working to reduce the fear of needles during vaccination. To reduce the fear and pain of this needle, American scientists have designed a 3D-printed vaccine patch. This will make it easier to vaccinate. The vaccine patch has been developed jointly by Stanford University and the University of North Carolina in the US. Its trial will be started soon. The first trial will be on animals. Scientists have sought approval in America for this.
Scientists claim that this vaccine patch gives an immune response 10 times faster than a needle in the hand. When the vaccine reaches the body with the help of the patch, the response of T-cells and antibodies has been faster than the vaccine injected into the hands.
Researchers say, with the help of this patch, the vaccine can be delivered directly to the immune cells of the skin. Which is the best condition for the vaccine to work. During the trial, the rat was vaccinated with the help of a patch and the antibody response was very fast.
The vaccine patch has very fine 3D printed microneedles (needles). The vaccine is applied by placing this patch on the skin. The pain felt with this needle is much less compared to the normal needle. The vaccine reaches the body directly through the skin with the help of a very fine needle.
Professor Joseph M DeSimone of Stanford University says, in the changing age of technology, we need to reduce the discomfort caused by the fear of needles. Along with this, the amount of vaccine dose can also be reduced. With the help of patches, people can be given a new vaccine. The special thing is that a person can apply it himself.
Scientists at the University of California Riverside in the US are developing such a plant that after eating, the vaccine will reach the human body. It will start with the Kovid vaccine. If you understand in easy language, then people will be given the vaccine of Covid by feeding them saplings.
Scientists are trying to transmit the mRNA vaccine of the corona to humans with the help of plants. According to researcher Juan Pablo of the University of California, a plant will make enough mRNA for a human and it can be vaccinated. Our goal is to reach the vaccine through plants, for this, we are growing spinach and lettuce in our garden.
10 percent of people are not getting the vaccine due to fear of needles. This has come to the fore in the Oxford Coronavirus Explanations, Attitudes, and Narratives survey. The fear of a needle is called a blood-injection injury. In people suffering from this, the blood pressure starts falling by the name of the needle, there is increased nervousness and restlessness. In many cases, the person even faints.
A survey conducted on 15,000 people in England revealed that a quarter of these people were afraid of needles. The youth and minorities are most afraid of needles. When the question of when to get the vaccine, when the people involved in the survey were asked, the answer was that they will get it done later or when they have the courage to get it done.
