The Drugs Controller General of India (DCGI) has given a green signal for the task of conducting a study on the mixing of India's two main COVID-19 vaccines, Covaxin and Covishield, news agency ANI reported on Wednesday, 11 August.

A Subject Expert Committee of the Central Drugs Standard Control Organisation (CDSCO) on July 29, recommended for conducting this study on mixing of the two shots.

The expert committee recommended granting permission to CMC, Vellore, for conducting the Phase-4 clinical trial which may conduct the study on 300 healthy volunteers by administered a dose of each of Covaxin and Covishield.

However, the DCGI's approval for the study on mixing the vaccines is different from the recent study of the Indian Council of Medical Research (ICMR) which concluded that combining two different shots is "safe and effective".
