Zycov-D: A Needle-Free COVID-19 Vaccine by Zydus Cadila


The COVID-19 pandemic has wreaked havoc on people’s lives worldwide, and finding a solution to combat the virus has become a top priority for researchers and pharmaceutical companies as reported in rajkotupdates.news : zydus needle free corona vaccine zycov d. In India, Zydus Cadila has developed a needle-free COVID-19 vaccine called Zycov-D. Recently, the Drug Controller General of India has approved this vaccine for emergency use. In this article, we will delve into the details of the Zycov-D vaccine and its potential impact on the fight against the pandemic.

What is the Zycov-D vaccine?

Zycov-D is a DNA-based vaccine developed by Zydus Cadila as reported in rajkotupdates.news : zydus needle free corona vaccine zycov d. Unlike traditional vaccines, which are administered using needles, Zycov-D is delivered through a needle-free applicator. This vaccine employs a plasmid DNA platform that allows it to generate an immune response against the virus.

How does the vaccine work?

Zycov-D works by delivering a small piece of the virus’s DNA into the body. This piece of DNA, known as a plasmid, contains the genetic code for the spike protein found on the surface of the coronavirus. Once the plasmid is inside the body, it instructs cells to produce the spike protein. The immune system recognizes the spike protein as foreign and produces antibodies to fight it.

What are the advantages of the Zycov-D vaccine?

The primary advantage of Zycov-D is its needle-free delivery system as reported in rajkotupdates.news : zydus needle free corona vaccine zycov d, which makes it easier to distribute and can increase vaccination rates. Additionally, the vaccine does not require extremely cold temperatures for storage, simplifying the logistics of vaccine distribution.

As with all vaccines, Zycov-D can cause side effects. The most common side effects include pain or swelling at the injection site, headache, fatigue, and fever. However, these side effects are generally mild and subside on their own within a few days.

How effective is the vaccine?

Clinical trials have shown that Zycov-D is safe and effective. In phase 3 trials, the vaccine was found to be 66.6% effective at preventing symptomatic COVID-19. Moreover, the vaccine was found to be 100% effective in preventing moderate to severe COVID-19.

Who is eligible to receive the vaccine?

The Zycov-D vaccine is currently approved for use in individuals 12 years of age and older. It is administered in two doses, with the second dose given 28 days after the first dose.


Zycov-D, a needle-free COVID-19 vaccine by Zydus Cadila, represents a significant step forward in the fight against the COVID-19 pandemic. Its needle-free delivery system and ease of distribution make it a promising option for increasing vaccination rates. Additionally, its efficacy in preventing moderate to severe COVID-19 is encouraging. As more people become vaccinated, we can hopefully bring an end to the pandemic and return to normalcy.
