Coronavirus India Live Updates: Covaxin Effectively Neutralises Delta Covid Variant, Says Top US Health Research Institute

The National Institute of Health said results of two studies of blood serum from people who had received Covaxin suggest that the vaccine generates antibodies that effectively neutralise the B.1.1.7 (Alpha) and B.1.617 (Delta) variants of SARS-CoV-2

India's Covaxin, developed by Bharat Biotech in collaboration with the Indian Council of Medical Research, effectively neutralises both Alpha and Delta variants of coronavirus, the US' National Institute of Health has said. The NIH said results of two studies of blood serum from people who had received Covaxin suggest that the vaccine generates antibodies that effectively neutralise the B.1.1.7 (Alpha) and B.1.617 (Delta) variants of SARS-CoV-2, first identified in the UK and India, respectively. The top American health research institute, which has a history of strong scientific collaboration with India, also said that an adjuvant developed with funding from it has contributed to the success of the highly efficacious Covaxin, which has been administered to roughly 25 million people till date in India and elsewhere. The single-day rise in fresh cases was recorded below 40,000 after 102 days, bringing India's COVID-19 infection tally to 3,03,16,897, while the daily fatalities remained below 1,000 for the second consecutive day, according to the Union Health Ministry data updated on Tuesday.
