New York: Many people are frightened when they see an injection needle during vaccination. Researchers around the world are currently considering different options to overcome this fear. Now American scientists have created a 3D printed vaccine patch. This will make vaccination easier and painless.
Researchers at Stanford University in the United States and the University of North Carolina have developed this vaccine patch. His trials will begin soon.
The first test will be performed on animals. Scientists have applied to the US administration for approval of the patch. If such a patch is applied to the penis instead of injecting it with a needle, the patch responds to the immune response ten times faster.
