An expert panel of India's central drug authority has recommended the permission for conducting phase-3 clinical trial of single-dose COVID-19 vaccine 'Sputnik Light' as a booster dose, official sources said on Saturday.
The recommendations have been sent to the Drugs Controller General of India (DCGI) for final approval.
The DCGI had on February 4 granted emergency use permission to Sputnik Light vaccine in India, subject to certain regulatory provisions.
