American scientists have done wonders using 3D technology. The latest way to inject without needles has been discovered. Developed a small band and thereby invented the vaccine injection process. Scientists who created the strip using 3D printing technology say it works more effectively than the vaccine given in injection form. In fact the vaccine works on any immune cells. It is said that by targeting the newly developed strip by hand it directly targets these cells and as a result gets better results.

Scientists claim that it is 10 times more effective than injection vaccine. It has also been found to increase the T-cell response of the immune system by up to 50 times. The strap is made by attaching 3D printed micro needles to the polymer strap. Joseph de Simon, who led the research team, said the micro-needles in the strips could be modified to accommodate the measles, influenza, hepatitis and Kovid-19 vaccines. He explained that the micro-needles attached to the strap would dissolve in the skin so that anyone could be vaccinated.
