> The Mu variant isn't competing very well against the Delta variant.
I think this logic only works if a Delta variant infection provides strong protections against Mu, and a large part of the unvaccinated and vaccinated population first gets exposed to delta variant (assuming it can spread easily...can't find R estimates for some reason, which seems crazy). After all, the same was said about delta before it was prolific, and this whole thing started with one person. "It's not very present, so it won't be present" doesn't make sense, only R numbers do.
