According to a Reuters article quoting CNBC-TV18, the Indian medicines regulator’s topic expert committee has recommended licensing Zydus Cadila’s three-dose COVID-19 vaccine (ZyCoV-D) for emergency use authorization (EUA). According to CNBC-TV18, the committee also stated that Zydus requires additional data for the 2-dose regimen of their vaccine.

On July 1, Cadila Healthcare Ltd., a generic medication manufacturer, submitted an application for the approval of its ZyCoV-D vaccine, citing a 66.6% efficacy rate in a late-stage trial involving more than 28,000 volunteers across the country. After the locally produced Covishield, the Bharat Biotech vaccine Covaxin, the Russian vaccine Sputnik V, and the American vaccine Moderna, ZyCoV-D would be the sixth vaccine to be approved for use in the country. It will also be the first DNA vaccination ever approved for use in any nation. The pharmaceutical company in Ahmedabad, India, submitted an emergency use authorization request for their ZyCoV-D three-dose COVID-19 vaccine on July 1.

A two-dose study protocol for the shot was also submitted by the business. The SEC will presumably evaluate the information and make a final determination. The business tested its COVID-19 vaccine in more than 50 locations across India, making it the country’s largest clinical trial to date. It was also the first time any COVID-19 vaccination had been tried out on teenagers in India, namely those between the ages of 12 and 18. 

Vaccine against ZyKV

ZyCoV-D is a plasmid DNA vaccine that generates an immune response via the cellular (T lymphocyte immunity) and humoral (antibody-mediated immunity) arms of the human immune system in order to protect against SARS-CoV-2 infection. There was a 100% success rate for mild disease after receiving the vaccination and a 66.6% success rate for symptomatic cases of COVID. A ‘needle-free injector’ is used to administer this vaccination intradermally. Zydus asserts that their needle-free technique can significantly cut down on adverse effects. Detailed information about ZyCoC-D is provided below.

The antidote

The new coronavirus SARS-CoV-2 causes COVID-19, and ZyCoV-D is the first ‘plasmid DNA’ vaccination against it. It’s the first plasmid DNA vaccination approved for use in humans. The vaccine “has proven its safety and efficacy profile” against COVID-19, Patel said in the company’s submission. It is estimated that Zydus Cadila spent between Rs 400 crore and Rs 500 crore on the vaccine’s research and development.


In order to stimulate an immunological response, ZyCoV-D uses the SARS-CoV-2 proteins’ genetic material to direct human cells to produce SARS-CoV2 antigen. The vaccine is stable between 2 and 8 degrees Celsius, which is ideal for the cold-chain infrastructure in India. It is more simpler to administer than intramuscularly administered vaccines since it is administered intradermally (in the space between the skin’s layers).DNA vaccines, which Cadila uses, have the potential benefit of being easily modified to protect against viruses that are constantly evolving.

To guarantee painless intradermal vaccine delivery, the three-dose immunization course is administered with a needle-free applicator called PharmaJet. Results with a two-dose regimen at 3 mg/dose were found to be equivalent to those from the existing three-dose regimen, so Zydus Cadila is “evaluating” this option as well.


On July 1st, the business announced that, pending necessary permits and production increases, the vaccine would be made available in 45-60 days. The new ZyCoV-D manufacturing plant is scheduled for completion by the end of July. Additionally, at its current facilities, it can manufacture 4.5 million doses. Zydus Cadila has said that it will produce 10-12 crore doses per year. With a goal of 200 million doses each year, the company is exploring potential partnerships to increase output by an additional 60-70 million.


On July 1, Zydus Cadila announced that the company had submitted a EUA application to the DCGI for their three-dose COVID-19 vaccine, dubbed “ZyCoV-D.” The Centre had informed the Supreme Court in an affidavit filed on June 27 that COVID-19 vaccinations, including Zydus Cadila’s candidate, “will be available for the 12-18 age group soon, subject to the statutory permissions.”
