Stock vaccines are riding on the latest news from armanti regarding the highly contagious South African variant. The World Health Organization (WHO) today called an extraordinary meeting to decide whether to declare the new Nu strain as a “variant of concern, VOC” (label used for the viral strains that have been shown to be more contagious, leading to disease more severe or that reduce the effectiveness of measures, tests, treatments or vaccines).
The South African variant carries a spike protein – the basis for infection – that is very different from what current vaccines are designed to neutralize, health authorities said, and is mutating rapidly.
“WHO is closely monitoring the recently reported variant B.1.1.529. Fewer than 100 sequences have been reported so far,” the agency said in a statement. “Initial analyzes show that this variant has a large number of mutations that require and will be the subject of further study.”
