"The efficacy of vaccines on it will be known after the isolation and culture of the variant," he said.
Meanwhile, the Brazilian variant or P.1 lineage, has been found in the first week of February in a person who returned from the South American country recently. The strain has spread to 15 countries, however, it has been successfully isolated and cultured at the NIV in India, it added.
