It depends on how contagious the disease is. I think the CDC estimate for COVID is at least 70% for herd immunity?
It doesn't mean it'll go away completely because there will probably be strains that the vaccine won't cover, but there won't be another epidemic because enough people are protected that it'll die out over time.
