Himedik.com – India has approved the use of Zydus Cadila’s Covid-19 vaccine against the Covid-19 coronavirus. Zydus Cadila’s is Covid-19 vaccine DNA first in the world.
According to an interim study cited by vaccine maker Cadila Healthcare, the DNA Covid-19 vaccine given in 3 doses can prevent symptomatic disease in 66 percent of the vaccinated population.
The company plans to make up to 120 million doses of a DNA Covid-19 vaccine, which will be distributed domestically every year. Previously, the efficacy of this DNA Covid-19 vaccine has worked well in animals, but there is not enough evidence in humans yet.
So far, India has given its citizens more than 570 million doses of the three approved Covid-19 vaccines, namely Covishield, Covaxin and Sputnik V vaccines.
Around 13 percent of adults who have had a complete Covid-19 vaccine injection and 47 percent have received at least one injection of the Covid-19 vaccine since early January 2021.
Cadila Healthcare said it had conducted the largest clinical trial of a DNA Covid-19 vaccine in India, involving 28,000 volunteers in more than 50 centres.
The company also claims for the first time that the Covid-19 vaccine has been tested on young people in India, of which 1,000 people fall into the 12-18 year age group. As a result, the Covid-19 DNA vaccine was proven safe and well tolerated by this age group.
The third phase of the DNA Covid-19 vaccine clinical trial will be conducted at the height of the second wave of the deadly Covid-19 coronavirus. However, vaccine makers believe that this DNA Covid-19 vaccine is quite effective against various variants of the corona virus, including varian Delta which is more contagious.
“I am quite happy with the Covid-19 DNA vaccine, because it offers a lot of good potential. If this is successful, then vaccination in the future will be logistically simpler,” said Prof Shahid Jameel, a renowned virologist quoted from BBC.
