Well that's great (/sarc), there won't be any vaccines developed and all the old diseases will come back with a vengeance.

Want to be crippled for life, hey don't bother with the polio vaccine, want to get TB, no problem. The flu, same thing.

Welcome to the new normal with leprosy, TB, Cholera, Typhoid, yellow fever, flu, plague and the host of super killers just waiting to get their hold again. Mother natures killers- ready for action!

Only problem is that idiots like you will be telling us that when they start hitting their straps and taking out chunks of the population that they were not some natural pestilence but, instead were some "bio engineered" (read some evil white guy in a lab somewhere) made it up to kill lots of "undesirables".
