New Delhi: The Drugs Controller General of India (DCGI) has reportedly given its approval for a study on mixing of Covaxin and Covishield Covid-19 vaccines in India. This study and its clinical trials will be conducted by Christian Medical College, Vellore.
A Subject Expert Committee of the Central Drugs Standard Control Organisation (CDSCO) had on 29 July recommended conducting this study. The expert committee recommended granting permission to CMC, Vellore for conducting the Phase-4 clinical trial covering 300 healthy volunteers for mixing of Covaxin and Covishield.
This study will be different from the one by the Indian Council of Medical Research (ICMR), which said mixing the two Covid vaccines elicited better safety and immunogenicity results.
The purpose of this study is to assess whether a person can be given two different vaccine shots — one each of Covishield and Covaxin — to complete the vaccination course.
