"In reality, for a vaccine to be effective, the portion of the population that needs to receive that vaccination is significantly less than 100%."
I'm curious to know if there have been results that show what sort of percentages of vaccination are needed to be safe from specific diseases. I presume this will vary between diseases as well as demographics.
