As various variants of Covid-19 started emerging, All India Institute of Medical Sciences director Dr Randeep Guleria has said that mixing doses of two different vaccines might increase its efficacy against Covid-19.
Dr Guleria told NDTV that fighting more infectious variants like Delta Plus and Delta is possible through mixing two different Covid-19 vaccines however, more data is required before a final approval is given to vaccine cocktail.
He said some data suggests mixing vaccines leads to slightly higher side effects, but other data suggests it may lead to better immunity and antibody protection.
Last month, the Centre said that under its new vaccination policy, government scientists will study various combinations of Covid-19 vaccine doses to see if this could lead to more efficacy.
