I am a self proclaimed nerd through and through I love science (especially astronomy and biology), Star Trek, video games, books of all kinds, and much, much more! Feel free to follow me and/or get to know me better! :)
Fuck, there goes my hot body. Time to change my name to The Abhorred Terrible Dread and go hide in my spiky goth fortress of doom forever. I’ll see you bitches when they invent Visine, and every second until then. Peace out!
Herd immunity is the idea that if enough people get immunized against a disease, they’ll create protection for even those who aren’t vaccinated. This is important to protect those who can’t get vaccinated, like immunocompromised children.
You can see in the image how low levels of vaccination lead to everyone getting infected. Medium levels slow down the progression of the illness, but they don’t offer robust protection to the unvaccinated. But once you get a high enough level of vaccination, the disease gets effectively road-blocked. It can’t spread fast enough because it encounters too many vaccinated individuals, and so the majority of the population (even the unvaccinated people) are protected.
