Vaccine maker Bharat Biotech and Indian Council of Medical Research (ICMR) have announced that Covaxin has been found to work against the UK-variant of SARS-CoV-2 virus.

The joint study conducted by Bharat Biotech and ICMR, published in bioRxiv, an open access preprint journal biological sciences, found that the Sera collected from Covaxin receipients neutralised UK-variants.

Earlier ICMR's National Institute of Virology (NIV), Pune isolated and cultured the UK variant of SARS-CoV-2 called as B.1.1.7. The ICMR-NIV strain was used for testing.

The B.1.1.7, a mutant variant from UK is known to have 50 percent higher transmissibility than the SARS-CoV-2  virus, making it huge cause of concern globally.  Earlier, Pfizer and Moderna have announced that their COVID-19 vaccines have produced neutralising antibodies against UK variant. Moderna said its vaccine was found to protect against B.1.351 variant which was detected in South Africa and is also highly transmissible.
Both UK and South Africa SARS-CoV-2 versions have multiple mutations on the spike protein, which the virus uses to enter cells.
