Exactly. We would not be having such a large increase in cases if only the FLiRT variants were around. This wave's driven by S31del and Q493E. (F456L has been universal for quite some time now, which is why it's a very good thing FDA recommended it for the updated vaccines.)

Front page @latimes KP.3.1.1. is not a FLiRT variant https://www.latimes.com/california/story/2024-08-19/californias-relentless-covid-surge-worsens-fueled-by-a-much-more-infectious-variant @ronlin (That's the problem. No R346T mutation. Instead there’s the Q493E mutation in KP.3 and, added to that, the S31 deletion in KP.3.1.1.)
