Drugs Controller General of India (DCGI) Dr V G Somani on Tuesday gave permission to Serum Institute of India to resume clinical trial of the Oxford COVID-19 vaccine candidate in the country while revoking its earlier order of suspending any new recruitment for phase two and three trial.

The DCGI, however, put certain conditions like taking extra care during screening, providing additional information in informed consent and close monitoring for adverse events during follow-up of the study which have to be "scrupulously" followed by Serum Institute of India (SII).
