I was going to ask whether "largely-but-not-completely bypasses" was an exaggeration, but the Israeli data really does suggest 39% effectiveness[0]! Everywhere else seems to be at least 70% or higher, so I wonder what's going on? Should the Israeli variant still be considered delta if it's much more effective at getting around the mRNA vaccines?

There was a version of the Israeli data that used the wrong denominator to calculate vaccine efficacy against Delta, and made things appear much worse than they were. I am unsure if this is that though, I have sort of lost track.

Yep, looks like it[0].

Maybe it’s me but I’m having trouble understanding their argument. It seems like they’re arguing that the vaxed cases came from cities and therefore the VE is not a reliable metric? (VE has many problems btw but we need to apply that standard both when the VE favors and disfavors the vaccine)
