In the original Batman movie, they contaminated the population not with one thing, but a combination of things found in multiple products
Cosmetics, deodorant, hairsprays, etc
Made the people go insane basically
Now look at what they're doing in real life
All the poisons in our products
And look at some of the people now
Along with the everyday stresses that everyday people endure
It's a recipe to get us where we are now
No single thing does anyone in
It's a combination of things
Including vaccines
