Like other vaccines, a DNA vaccine, once administered, teaches the body's immune system to fight the real virus.
ZyCoV-D uses plasmids or small rings of DNA, that contain genetic information, to deliver the jab between two layers of the skin.
The plasmids carry information to the cells to make the "spike protein", which the virus uses to latch on and enter human cells.
Most Covid-19 vaccines work by giving the body instructions to make a fragment of the spike protein so it can trigger a person's immune system to produce antibodies and teach itself to fight off the virus.
