Fig 2 — The upper panels show the observed incidence of symptomatic cholera cases adjusted for under-reporting (orange), the model-fitted incidence of symptomatic cases (dark green), and both symptomatic and asymptomatic infections (light green) from October 2010 to April 2014, without (A) and with (B) vaccine intervention initiated on November 17, 2010 (five weeks after the onset of the epidemic). The numbers of susceptible (purple) and vaccinated (pink) individuals are shown in the lower panels, without (C) and with (D) vaccine intervention. The average waiting time for a susceptible individual to be vaccinated is 50 weeks, the vaccine efficacy is 60%, and the average duration of protective immunity is three years.
