I did, and that's true. If only 3/4 of the population were immunized, we'd still have all the diseases that we currently have abolished. They would be endemic. They would be infecting both people who HAVE HAD vaccinations and those who haven't. They would have time to mutate, infect more people.<quoted text>
DOCTOR Nuggin, you wrote: "If 3/4 of a population is immunized, it's the same as having ZERO people immunized", did you not, sir?!
We'd have no herd immunity at that level. The threshold for herd immunity is MUCH higher than 75% of the population. ESPECIALLY when dealing with urban population centers and schools full of children.
