A recent announcement by HRD minister of state, Shashi Tharoor, was about the design and successful testing of a novel concept of needleless vaccine delivery system developed by the Indian Institute of Science (IISc). IISc happens to be the first and only organization to have come out with this device.
Tests conducted on mice in laboratories, showed successful delivery of typhoid vaccines using this novel method. This method employs instantaneous mechanical impulse generated by micro-blast waves. The delivery of vaccines into mice is subcutaneous.
In this method, animals have a painless experience during vaccine delivery. Further, lesser quantity of vaccines is enough to provide protection to animals against infection, as compared to conventional methods.
Further, this new system is full of benefits as it is easily portable, safe, economical and disposable.
