Mutations in coronavirus are sporadic and single mutations are not found to be dominant in any particular area in India, Indian Council of Medical Research director general Balram Bhargava said, clarifying that there was no Indian variant of coronavirus.
Bhargava maintained that both Covaxin and Covishield were effective against the UK and Brazilian variants, while work against the South African strain was on.
“All viruses drift as the virus replicates itself but the changes that occur due to this process are not important,” health secretary Rajesh Bhushan said. “However, when a virus shifts, it undergoes significant changes and there is a need to test whether my existing vaccines work against the virus, known as variant or mutant virus,” he added.
