You're conflating cVDPV with WPV. Despite both having a "type 2", they are not the same virus.

Calling a few hundred reported cases a year globally "very, very common" is... a stretch. You have better odds of getting struck by lightning.

I am not conflating cVDPV with WPV. The parent comment claimed type 2 and type 3 polio were gone, which is not true. WPV 3 and WPV 2 are gone, but type 2 and type 3 polio are both still around. If you get polio today (unlikely but possible), there's a pretty good chance it's cVDPV 2.

So you you're saying you knew the two types of polio were eradicated but inexplicably assumed the parent comment must have meant the vaccine-derived poliovirus was eradicated. Or you think these are the same virus because you saw "type 2" in the names of both.

I don't think these are the same thing. But when someone says that polio type 2 has been eradicated, that means the entire family of WPV, cVDPV, and VAPP. Not just WPV.

For all intents and purposes, yes, cVDPV is the same thing as WPV. There have actually been instances where cVDPVs have evolved into things that look quite a bit like WPV. Declaring victory over "type 2/3" because WPV is gone is meaningless when lots of people still get cVDPV and have exactly the same symptoms.
