Coronavirus: Mu Variant In Los Angeles

The big concern recently has been the Delta variant. Is is possible that the Mu variant will be the next big variant concern? There are some signs it could be. 

 Deadline (Sep 3) reports:

Today, the Los Angeles County Department of Public Health announced the Mu variant, for the first time, has been identified in the region. The numbers are still small; Only 167 Mu variants have been identified in L.A. County thus far. “These specimens were sequenced between June 19 and Augusts 21, with the majority of Mu specimens sequenced in July,” according to a statement from county public health officials.

Note: did some grammar clean-up to the above as it was a bit messy.

First off, there aren't that many cases of it, but . . .

Speaking of Mu [Dr. Anthony] Fauci said, “This variant has a constellation of mutations that suggests that it would evade certain antibodies, not only monoclonal antibodies, but vaccine- and convalescent serum-induced antibodies . . . But there isn’t a lot of clinical data to suggest that. It is mostly laboratory in-vitro data.”

My Google search indicates that monoclonal antibodies would be Regeneron. A preliminary search didn't really give me any easy definitions of convalescent serum-induced antibodies. The mention about vaccines is what will peak the attention of most of us.

Is it possible that this new variant will evade current vaccines as well as certain therapeutics? Is that what I'm reading? If so, definitely something to keep tabs on and hopefully this laboratory evidence doesn't end up translating to real world fact.
