This bubble started well before Covid. I do agree that if the vaccination campaign is successful the mood will be such that it might sustain it a little longer. That should factor into the calculation. Though on the other hand, governments may hold back a little on stimulus once that happens as they've been throwing money all over the place during Covid.
