The World Health Organization (WHO) has started to monitor new mutations of the coronavirus known as Mu strain that can be resistant to the vaccines as France 24 reported.

“The Mu variant has a constellation of mutations that indicate potential properties of immune escape," the bulletin said.

The WHO noted that the qualities of this type of virus contain the risk of resistance to the vaccines but further researchers needed to understand its peculiarities better.
