US SAYS COVAXIN EFFECTIVE AGAINST ALPHA & DELTA COVID-19 VARIANTS

  • 30/06/2021

India’s Covaxin, developed by Bharat Biotech in partnership with the Indian Council of Medical Research against the COVID-19 virus has successfully neutralized the Alpha and Delta variant of the virus, said the US National Institute of Health. The Alpha and Delta variants of the CVID-19 virus was first discovered in UK and India respectively.

Covaxin is a non-replicating version of SARS-CoV-2 that induces the immune system to produce antibodies against the virus. The vaccine is safe and well-tolerated, according to published results from a phase 2 trial, according to the NIH, which added that safety data from a phase 3 trial of Covaxin will be available later this year.

‘Meanwhile, unpublished interim results from the phase 3 trial indicate that the vaccine has 78 per cent efficacy against symptomatic disease, 100 per cent efficacy against severe COVID-19, including hospitalization, and 70 per cent efficacy against asymptomatic infection with SARS-CoV-2, the virus that causes COVID-19,’ said the US NIH.
