Reading the article page, it says that only Nick is known to have endured it; plus, it seems like all the wessen have some trait much better than normal humans, and they all connect to mythological creatures.

So I figured that perhaps the Cracher-Mortel toxin only triggered his body to "mature" a/the woge, as a possibility that the grimms are simply a more human looking wessen(but only time will tell in that regard).
