Yes, but then there's Measles. I cry internally for those kids who died (along with so many others such as in Palestine, but now I'm just being too sad).

You have to understand it to be able to be successful at stopping it every time. Ticks are easy to understand, and even after well over 50 years of sabotaging the education system, no culture completely forgets the discovery of the viruses/bacteria we can't see without microscopes in just a few generations. When you tell someone "we found god's definition of us inside our own bodies, and it really is unique per person", religious zealots tend to care (even if it's because they want to prevent someone else knowing things).

Unfortunately, somehow "It's just Measles" became a thing, as if the Human Rhinovirus (Common Cold "Nose Virus" that lives in your sinuses 24/7/365) they're mistaking it for can't kill someone with a weakened immune system.
