An expert panel of India’s drug regulator has recommended relaxing norms for the use of a government-backed coronavirus vaccine after it was found to be highly effective in a late-stage trial, the regulator said on its website on Thursday.

Bharat Biotech’s vaccine showed an 81 percent efficacy in preventing symptomatic COVID-19 in an interim analysis of a late-stage trial in India, the Central Drugs Standard Control Organization said last week.

“After detailed deliberation, the committee recommended for omission of the condition of the use of the vaccine in clinical trial mode”.

“However, the vaccine should be continued to be used under restricted use in emergency situation condition.”
