New Delhi, Sept. 22 -- Scientists at the CSIR-Centre for Cellular and Molecular Biology (CCMB) in Hyderabad have analysed more than 2,000 SARS-CoV-2, the virus that causes Covid-19 genomes from India available in the public domain to understand the various strains in circulation.

The clade or genetic group circulating in India has 70 per cent similarity with the major strain around the world, hence , one vaccine or drug is sufficient to fight it, they said.

Earlier in June, the team had revealed the presence of a distinct virus population among Indians. This was named the clade I/A3i, and is recognised by the presence of 4 specific variations in their genetic makeup (genomes).

At that time, 41 per cent of all Indian SARS-CoV-2 genomes be...
