Success rate of two allocation strategies in minimizing the total population prevalence in a two-sex transmission model without natural immunity.

The success rate of an allocation strategy is calculated as the percentage of random parameter combinations for which this strategy achieves the largest reduction in the total population prevalence of infection. n = 10,000 random combinations of sex-specific recovery rates α and transmission probabilities β were drawn from uniform distributions between 0 and 1, conditional on R0>1 with contact rate c = 1 and death rate d = 0.02 deaths per year. Allocation strategies were evaluated at 5% and 95% of the critical immunization coverage vc required for elimination of infection from the heterosexual population.
