I remember an interesting HIV campaign that went something like

UVL=0VL

It made me think.

(undetectable viral load = zero viral load)

Perhaps this vaccine will not cure HIV once and for all just yet, but maybe it can work as an alternative to PrEP by keeping the viral load down?

I think you're thinking of "U=U", which stands for "undetectable = untransmittable". At this point in the epidemic, most transmission happens from people who don't know their status, and not from people who are known to be HIV+ and are in treatment.
