The Covid-19 vaccine developed by Indian pharmaceutical firm Bharat Biotech has been found to be 78% effective in preventing symptoms of Covid-19 and 100% against severe disease in stage three trials, the company said.

In a press release on Wednesday, Bharat Biotech published second-round interim results from stage-three trials of the country’s first indigenous Covid-19 jab. The data, which was based on a trial of more than 25,000 participants, showed the formulation to have 78% efficacy in preventing symptomatic Covid-19 – and totally effective in preventing severe forms of the disease.
