The world is currently grappling with the COVID-19 pandemic, & vaccination is seen as the only way out of this crisis. India has been at the forefront of the fight against COVID-19, & Indian pharmaceutical companies have played a critical role in developing vaccines to tackle the virus. One such vaccine is the Zycov-D, a needle-free corona vaccine developed by Zydus Cadila, a leading pharmaceutical company based in Gujarat. In this article, we will explore the features, benefits, & effectiveness of the Zycov-D vaccine.
The Zycov-D vaccine is a DNA-based vaccine that is administered through a needle-free injection. The vaccine is administered using a jet injector, which uses high pressure to deliver the vaccine into the body. This method of delivery is painless & does not require the use of needles, making it ideal for people who are afraid of needles.
How the Zycov-D Vaccine Works
The Zycov-D vaccine works by introducing a small piece of DNA from the COVID-19 virus into the body. This piece of DNA instructs the body to produce a protein that is found on the surface of the virus. Once the protein is produced, the body’s immune system recognizes it as a foreign invader & produces antibodies to fight it. These antibodies remain in the body & are able to recognize & fight the actual virus if the person is infected.
Advantages of the Zycov-D Vaccine
The Zycov-D vaccine has several advantages over traditional vaccines. Firstly, it does not require the use of needles, which makes it painless & more comfortable for patients. Secondly, the vaccine can be stored at room temperature, which makes it easier to transport & store. Traditional vaccines require refrigeration, which can be a challenge in countries with limited infrastructure. Finally, the vaccine has been shown to be effective against new strains of the virus, including the highly contagious Delta variant.
Clinical Trials of the Zycov-D Vaccine
The Zycov-D vaccine has undergone extensive clinical trials to ensure its safety and efficacy. The Phase 1 & 2 clinical trials were conducted on over 1,000 participants, and the vaccine was found to be safe & well-tolerated. The Phase 3 clinical trial was conducted on over 28,000 participants, & the vaccine was found to be 66.6% effective against symptomatic COVID-19. The vaccine was also found to be 100% effective against moderate to severe COVID-19.
