The coronavirus strain B. 1. 617, first identified in India, has mutations that increase its transmission. It can also be resistant to antibodies, which gives it a wide opportunity to re-infect people.
However, vaccination will still be able to reduce its transmission, prevent severe forms of the disease and prevent the death of patients. The World Health Organization's (WHO) Chief scientific officer, Dr. Semya Swaminathan, acknowledged that the Indian version is of great concern to her.
The strain copes with antibodies obtained both naturally and by vaccination.
вЂњThis is an extremely fastвЂ”spreading option,вЂќ Swaminathan said.
The US Centers for Disease Control and Prevention has not yet named the Indian strain as вЂњof concernвЂќ as the British or South African variants. But recommended restricting travel from India and on May 4, the White House banned most travel.
