Zycov-D The Needle Free COVID Vaccine by Zydus

Zydus Cadila, one of India’s leading pharmaceutical companies, has recently launched its needle-free COVID-19 vaccine, Zycov-D, in the city of Rajkot. The company has received approval from the Drug Controller General of India (DCGI) to conduct clinical trials of this vaccine, and it is expected to be a game-changer in the fight against the pandemic.

This article will discuss the Zycov-D vaccine in detail, including its features, efficacy, safety, availability, and its potential impact on India’s vaccination drive.

Introduction to Zycov-D

The COVID-19 pandemic has wreaked havoc across the globe, infecting millions of people and causing numerous deaths. Governments and medical organizations have been working tirelessly to develop a vaccine that can prevent the spread of the virus. In this regard, Zydus Cadila has made a significant contribution by launching its needle-free COVID-19 vaccine, Zycov-D.

Features of Zycov-D

Zycov-D is a plasmid DNA vaccine that is administered using a needle-free injector called the PharmaJet® Stratis® Needle-Free Injection System. This system uses a high-pressure stream of liquid to deliver the vaccine directly into the muscle tissue, eliminating the need for a needle.

The vaccine is stored at 2-8°C, making it easier to transport and store than other vaccines that require ultra-cold storage temperatures. This feature makes it especially suitable for use in remote and rural areas where cold chain infrastructure is not readily available.

Efficacy of Zycov-D

Zycov-D has shown promising results in preclinical studies, and it has been found to be safe and effective in preventing COVID-19. The vaccine triggers the production of antibodies that neutralize the virus and prevent it from infecting cells.

Zydus Cadila has conducted phase 1 and 2 clinical trials of the vaccine, which have shown that it is safe and well-tolerated. The company is currently conducting phase 3 clinical trials to evaluate the vaccine’s efficacy in a larger population. The interim analysis of the phase 3 trials has shown that the vaccine has an efficacy rate of 66.6% against symptomatic COVID-19.

Safety of Zycov-D

Zycov-D has been designed to be safe and well-tolerated. The vaccine does not contain any live virus, and it cannot cause COVID-19. It has undergone rigorous testing to ensure its safety, and the clinical trials conducted so far have not shown any serious adverse effects.

Availability of Zycov-D

Zydus Cadila plans to manufacture 240 million doses of Zycov-D annually. The vaccine will be available in two doses, and the company is expected to price it competitively to make it accessible to everyone. The launch of Zycov-D in Rajkot is just the beginning, and the company plans to roll out the vaccine in other parts of India soon.

The Indian government has granted emergency use authorization to Zycov-D, making it the sixth vaccine to be authorized for use in India. The vaccine is expected to play a significant role in India’s vaccination drive, which aims to vaccinate the entire adult population by the end of the year.
