Not sure why people downvote this, it's objectively correct. We bred these dogs to be what they are, we can absolutely breed something else to take its place. This is really basic evolution and trait selection.
I think they're great looking dogs, but I also think they need a similar ban in the US, barring a few highly specialized breeders, who can essentially reverse what was done to them over a period of generations. I don't want to see them go away entirely, I'd just like them controlled until we can breed out what we've bred in.
The link seems obvious, honestly. If you get a vaccine, that's .5ml adding to your body weight... you go get in a pool without factoring that in, next thing you know, you're at the bottom running out of air. If he ate within half an hour of getting in... well, he was just courting death at that point.
