Zydus Cadila: What we know about India’s new Covid vaccines

The ZyCoV-D vaccine is also the world’s first DNA vaccine against Covid-19.

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.

ZyCov-D is also India’s first needle-free Covid-19 jab.

It is administered with a disposable needle-free injector, which uses a narrow stream of the fluid to penetrate the skin and deliver the jab to the proper tissue.


India has given a boost to its vaccination programme by approving its first vaccine for those under 18.
