Corona virus changed & became double mutant & at times even took the shape of triple mutant. Those virus according to virologist Sahid Zamil, can be checked through vaccination. According to him, the research over the same made by “the cellular & molecular biology” as reported that covid virus’s another variant B.1.617 is equal with double & triple mutant for which this virus enter into the body easily. Some specialists are with the view that whenever anybody feels that he or she is corona positive; first of all the strength of immunity power should be examined & whether the person concerned is suffering with diabetics or high blood pressure should be examined.
