The announcement by Union Health Minister Mansukh Mandaviya on Tuesday came a day after the Subject Expert Committee (SEC) on COVID-19 of the Central Drugs Standard Control Organisation (CDSCO) recommended granting emergency use authorisation (EUA) to the COVID-19 vaccines Covovax and Corbevax with certain conditions.

The committee also had recommended granting restricted emergency use approval to the drug Molnupiravir for treatment of adult patients with COVID-19 and who have high risk of progression of the disease.

In a tweet, the minister said, “Congratulations India. Further strengthening the fight against COVID-19, CDSCO, @MoHFW_INDIA has given 3 approvals in a single day for: – CORBEVAX vaccine – COVOVAX vaccine – Anti-viral drug Molnupiravir For restricted use in emergency situation”.
