Are the 45% (with HUGE error bars btw) protective effect for reinfection with BA.1 referring to the protective effect where the first infection is BA.1 and the second infection is BA.1, or where the first infection is any variant and the second infection is BA.1?
It's not surprising that "old" variants don't result in protection against BA.1, but it would be a bit surprising to me if BA.1 didn't trigger protection against BA.1
