ZyCoV-D vaccine ZyCoV-D is a plasmid DNA vaccine that produces the spike protein of the SARS-CoV-2 and elicits an immune response mediated by the cellular (T lymphocytes immunity) and humoral (antibody-mediated immunity) arms of the human immune system.
The vaccine has shown theefficacy of 66.6% against symptomatic Covid cases and 100% for moderate disease. It is an intradermal vaccine, applied using a ‘needle-free injector’.
Zydus claims the needle-free system can lead to a significant reduction in side effects. .Never miss a story! Stay connected and informed with Mint.
