Covaxin and covisheild 50% less effective in India (B.1.617 variant)

According to a series of reports authored by a scientist at the India Council of Medical Research, the Vaccines covishield and covaxin are expected to generate only half antibodies against the B.1.617 strain. When compared with the previous virus strain, antibodies will be Halved. This B.1.617 strain is especially found in India. As well as declared as the third variance of concern by the who.
