Well, the pox, diphteria and polio are gone or almost gone due to vaccinations, at one point or the other we had herd immunity with those. Its just that some small pockets of society refused to vaccinate and played incubators, so the rest of us wouldn't miss all the "fun"...
Quite the same for all the other diseases you enumerated, just that we never managed to get herd immunity due to antivaxxers ruining it.

"It's actually an interesting conundrum. The very tool you are using for [polio] eradication is causing the problem"
- corty 6y agoYes, the oral polio vaccine is a live vaccine that can cause polio. More advanced vaccines, practically everything in use in developed countries nowadays, don't contain live virus. It's just that third-world countries cannot afford better vaccines. So yes, you are right that there are some corner cases.
