"Chances of the vaccine being less than 50% effective are remote, as suggested by our trial results so far," the company, which is developing Covaxin in collaboration with the Indian Council of Medical Research (ICMR)- National Institute of Virology (NIV), was quoted as saying. The vaccine is currently in phase 3 trials. This is India's first phase-3 efficacy study for a COVID-19 vaccine.

News18 also quoted President of Quality Operations at Bharat Biotech Sai D Prasad saying that WHO, United States Food and Drug Administration (USFDA), and India's Central Drugs Standard Control Organisation (CDSCO) have approved a respiratory disease vaccine if it was at least 50 percent effective. Bharat Biotech aims to roll-out Covaxin by mid-2021 after receiving approvals.
