Further, the report also stated that the vaccine will be 93.4 per cent effective against those who have severe symptoms of Covid-19.
"Safety analysis demonstrates adverse events reported were similar to placebo, with 12 per cent of subjects experiencing commonly known side effects and less than 0.5 per cent of subjects experiencing serious adverse events," it said.
"Efficacy data demonstrates 63.6 per cent protection against asymptomatic COVID-19, 65.2 per cent protection against the SARS-CoV-2, B.1.617.2 Delta and 70.8 per cent protection against all variants of SARS-CoV-2 virus," Bharat Biotech added.

"I am delighted to see that the phase III efficacy data has also been published in the Lancet. This itself speaks high about the strong position of Covaxin amongst other global front-runners COVID-19 vaccines," Dr Balram Bhargava, Director General, Indian Council of Medical Research (ICMR) said.
"The bench to bedside journey of Covaxin in less than 10 months showcases the immense strength of "Atmanirbhar Bharat" along with the Indian academia and industry in fighting against the odds and carving a niche in the global community," Bhargava added.
