A study by researchers from the National Institute of Virology in Pune, the Indian Council of Medical Research and vaccine manufacturer Bharat Biotech found that Covaxin is effective against the beta and delta variants of Covid-19.
The Delta variant (B.1.617.2) was first found in India and is the dominant variety here. On the other hand, the beta variant (B.1.351) was first discovered in South Africa.
The Delta variant is considered highly contagious and is one of the main causes of devastating second wave in India. However, there is still no evidence that this variant causes more deaths or serious cases.
