COPENHAGEN, Nov. 7 (Xinhua) -- The World Health Organization's (WHO) Regional Director for Europe, Dr. Hans Kluge, on Saturday calmed concerns that the so-called "cluster 5" mutation of mink-related coronavirus found in Denmark might affect vaccine development.
"It is a realistic question to ask whether 'cluster 5' can harm a vaccine. Right now, there is no reason to say that it will harm the development of a vaccine. But it needs to be investigated. Because it's a new combination. 'Cluster 5' is a new element," Kluge said at a hastily-convened press briefing at the Danish health ministry on Saturday.
