Coronavirus: Zydus Cadila seeks approval for needle-free COVID vaccine; Here’s how it works


Unlike any other COVID vaccine, Zydus Cadila is currently seeking approval for its needle-free vaccine, which will use the ‘Jet Injector’ technique to administer the three doses. Rather than injecting the drug by piercing into the skin, the vaccine will use high-pressure to inject the liquid directly through the upper layer of the skin and into the underlying tissues.

While it may seem like a new discovery into the world of vaccines, it is an old technique, first demonstrated in 1866. This method of vaccination was also used during the 1960s for smallpox vaccination drives.

As far as needle-free vaccines are concerned, they can reduce the risk of arm soreness which is very prevalent in intramuscular injections and can also limit the emergence of side effects.
