How so, if most of them have never before been exposed to monkeypox? I'm not speculating that they are spreading cow pox from the live vaccine, but that today, they are being exposed to monkey pox, and, due to prior vaccination, having an extremely mild case that they don't notice, but that's contagious.
Essentially, in all documented cases, vaccination for orthopoxvirus with the vaccines currently or historically available has been completely neutalizing/sterilizing. This virus changes very little, although there's some interesting evidence of base substitutions due to interaction with the human immune system. The implications of this remain to be discerned.
Is it possibly that some older people, who were vaccinated decades ago, are spreading monkeypox asymptomatically?
Unlikely. That transmission mode would have been exhausted long ago.

There's no evidence of this, and the article says as much. I have to wonder why you are bringing this up.

Are environmental stability (bad) and long term sterilizing immunity (good) two sides of the same coin?
