Some Weeks To Test Vaccine Against Mutant Virus: WHO Scientist To NDTV

A mutant strain of the novel coronavirus - first identified in the UK in September and which is rapidly replacing other variations of the virus - may already be present in several countries, Dr Soumya Swaminathan, Chief Scientist at the World Health Organisation, told NDTV Monday night. However, she also said it is still too early to draw conclusions about the new strain - which initial data suggests is up to 70 per cent more transmissible - and that it is "unlikely a couple of mutations" could affect the immune system's response to one of the existing Covid vaccines.
