“An effectiveness result of 50 per cent achieved during the peak Covid-19 delta variant wave in India, in a high risk study population of physicians and healthcare workers, in a hospital environment, and who are challenged with high viral loads, provides insights into the efficacy and effectiveness of Covaxin,” the company said.
