<p>India's first DNA vaccine against Covid-19 showed 66% efficacy against the disease without any incidence of death or severe illness during clinical trials on 28,000 individuals, its developer Zydus Cadila claimed on Thursday.</p>.<p>The company has applied for Emergency Use Authorization for the vaccine ZyCoV-D from the Central Drug Standard Control Organisation sharing the clinical trial data with the regulator, which would take a call on the EUA approval after scrutinising the information.</p>.<p>As a part of the clinical trial, the indigenous vaccine was tested on 1,000 children of 12-18 years of age. This is the first trial in India on children, who according to some experts may be at greater risk during the third wave in the absence of vaccination, which is now restricted to individuals above 18 years.</p>.<p>While the safety and tolerability data from the kids' trial had been shared with the CDSCO, the company would take at least another four weeks to submit the immune response data to the regulator, said Sharvil Patel, managing director, Cadila Healthcare. The tolerability profile was similar to that seen in the adult population.</p>.<p><strong>Also Read | <a href="https://www.deccanherald.com/international/world-bank-says-will-boost-covid-19-vaccine-funding-to-20-billion-1003444.html" target="_blank">World Bank says will boost Covid-19 vaccine funding to $20 billion</a></strong></p>.<p>During the trial, carried out at 50 sites, the investigators evaluated a two-dose as well as a three-dose regimen of the vaccine.
