I was under the impression that vaccination ratios need to be at a level to prevent an outbreak amongst those that aren’t vaccinated rather than to protect those that are vaccinated. I. E. From a purely selfish viewpoint some idiot’s lack of vaccination is their problem not the vaccinated.
Kind of (actually, just read the above post, which sort of covers it).
Being vaccinated prevents (hopefully) you getting infected, but also prevents you spreading it.
Some people can’t be vaccinated – immunocompromised, very young/old/CatAIDSy types.
If enough people are vaccinated, the disease simply can’t ‘carry’ near to the non-vaccinated people.
Basically, there’s two types of people who aren’t vaccinated:
-those who medically can’t, and
-crazies (or more fairly, crazy parents)
