Herd immunity means that if you reach a certain threshold of immune individuals in a community, say 90%, those who are susceptible to infection get some protection because it is so hard for an infection to spread. Too many links in the chain are broken for an epidemic to start. It doesn’t mean an individual who is not immune can’t get sick occasionally.
So herd immunity means an epidemic is unlikely?
