> OPV2 (specifically 2) cures zero infections because type 2 is extinct in the wild. So explain how my sentence isn't true?
OPV2 prevents cvdpv2 infections. This is a virus similar in all respects to wpv2, except its lower rate of paralysis onset. It's effectively the same disease, just like in my forest fire analogy.
Before the advent of nOPV2, OPV2 was much more effective at this than any other option. So you could not simply cease OPV2 production, post 2016 it was targeted to cvdpv2 hotspots only.
