New Covid variant named Mu

[Carey]

Mu was first noted in January of this year - one month after Lamba, so not actually "new" & like Lambda has been noted as a WHO VOIs (thus the naming of this variant)... both originated in South America
At least 49 states have verified cases of Mu (& cases have been falling since July unlike some of the Variants of Concern (VOC)) & it is more wide spread in South America... as a VOI, it is not as worrisome for the regulators as VOCs that have not shown reductions & have gone beyond the initial, which for Mu indicates:"Early research from Italy shows mu is susceptible to antibodies produced by the Pfizer-BioNTech vaccine, but they don't work as well as they do against the original strain or alpha variant. Early research from the U.K. found specific mutations may help mu escape the immune system."
When you read through this list you will see "may" in most of the variants... that is a POTENTIAL of the variant, that makes it a VOI, not necessarily what WILL happen in real life... Early research in 2 countries with far different vaccine status can give remarkably different results... which is why we have the more ambiguous terms "may", "uncertain" rather than the wording that the OP chose to use!
