Figure 3. Smallpox infection and death rates over time considering different immunologic factors included in model, New York, NY, USA, and Sydney, Australia. Characteristics (e.g., size, age, immunosuppression rates) of populations from 2015 were used. A) Rates for New York, considering different levels (none, base case, and high) of residual vaccine immunity with the inclusion of immunosuppressed population. B) Rates for Sydney, considering different levels (none, base case, and high) of residual vaccine immunity with the inclusion of immunosuppressed population. C) Rates for New York, including and excluding immunosuppression with base case level of residual vaccine immunity. D) Rates for Sydney, including and excluding immunosuppression with base case level of residual vaccine immunity.
