The consensus one year ago was that immunity doesn’t last longer than 6 months (hint: it does). I’ve learned to mostly disregard “expert opinion”, especially when they’re talking straight out of their asses as in this case (we haven’t had the vaccine long enough yet to have any kind of experimentally informed view on this topic).

No, it wasn’t.
The consensus was that it was uncertain the degree and duration of immunity conferred because the available evidence was insufficient and contradictory.
