whole population is susceptible. What happens to the critical immunization threshold as R0 gets larger (more individuals are infected by an infected individual)? Consider the formula in Section 3 of SimUText's How Diseases Spread that relates the critical immunization threshold, pcand the Basic Reproductive Number R0. Recall that the critical immunization threshold is the minimum proportion of the population that must be vaccinated to establish herd immunity; and The Basic Reproductive Number is the average number of individuals infected by an infected individual, if the whole population is susceptible. What happens to the critical immunization threshold as R0gets larger (more individuals are infected by an infected individual)? A. None of the other answers in this list is correct. B. The threshold pc approaches 1 (100%). C. The critical immunization threshold exceeds 100%. D. The threshold pc approaches 0. E. The threshold pc approaches 0.5.
