To slide around a little bit….
No -'this'- is how you are supposed to think.
The plague was real. Smallpox was real. Malaria and other diseases are real and we are their food. You kids don't even have to worry about chickenpox anymore - an illness that was pretty much part of being alive. You got it at some point as a kid.
Frivolous vaccination campaigns against the flu and the success of vaccines for mumps and rubella have made the threat all seem like a distant dream.
We have eradicated, from our society, diseases that still ravage other parts of the world. Both because of hygiene/pest control, and because of aggressive vaccination plans.
I am not saying that people should be forced to be vaccinated - but that the idea they are all useless is part of the goal to eradicate knowledge of history from society.
