The World Health Organization has added another version of coronavirus to its list of “variants of interest” amid concerns that it may partially evade the immunity people have developed from past infection or vaccination.
The Mu variant, also known as B.1.621, was added to the WHO’s watchlist on 30 August after it was detected in 39 countries and found to possess a cluster of mutations that may make it less susceptible to the immune protection many have acquired.
According to the WHO’s weekly bulletin on the pandemic, the Mu variant “has a constellation of mutations that indicate potential properties of immune escape”. Preliminary data suggests it may evade immune defences in a similar way to the Beta variant first discovered in South Africa, the report adds, but this needs to be confirmed by further work.
