Happy to look at a link.
I understand some diseases can still be caught from contaminated soil, foods or animals, thus posing a risk to someone who has not received the vaccine even if everyone else is protected. If that is the case for measles then I will stand corrected. However, it is not for many others where proper immunity by the community does result in eradication.
