In this regard, Zydus Cadila has developed a revolutionary needle-free corona vaccine called Zycov-D. In this article, we will explore the various aspects of this vaccine, including its efficacy, safety, & availability!

The COVID-19 pandemic has wreaked havoc across the globe, leading to a massive loss of life, & widespread economic disruption. The only way to tackle this pandemic is through vaccination. Vaccines have proven to be an effective tool in controlling infectious diseases, & the race to develop a vaccine against COVID-19 has been a top priority for researchers worldwide.

Zydus Cadila

Zydus Cadila is a leading Indian pharmaceutical company that has been at the forefront of developing COVID-19 vaccines. The company has developed a novel, needle-free corona vaccine called Zycov-D, which has been hailed as a game-changer in the fight against COVID-19!


Zycov-D is a plasmid DNA vaccine that is administered through a needle-free device called the PharmaJet. The vaccine is administered intradermally, which means it is injected into the skin instead of the muscle, as is the case with traditional vaccines. This makes it a needle-free vaccine, which is a significant advantage over traditional vaccines!

How does Zycov-D work?

Zycov-D works by introducing a small piece of the COVID-19 virus’s genetic material into the body. This genetic material instructs the body’s cells to produce a harmless piece of the virus called the spike protein. The immune system recognizes the spike protein as foreign & produces antibodies to attack it. If the person is later exposed to the COVID-19 virus, these antibodies will recognize & attack the virus, preventing infection.

Efficacy of Zycov-D

Zydus Cadila conducted clinical trials of Zycov-D on over 28,000 participants, making it the largest clinical trial of a COVID-19 vaccine in India to date. The results of the clinical trial showed that Zycov-D was safe & well-tolerated & had an efficacy rate of 66.6%.
