Mathematical models that take into account the interplay between human behaviour, economics, and disease ecology may be more useful in understanding the dynamics and spread of diseases than models that rely on epidemiology alone. The transmission and control of infectious disease is strongly influenced by how people make choices, both individually and collectively, when presented with opportunities to engage in preventive actions or to use preventive health care services. The effectiveness of the TB vaccine in preventing TB is controversial; studies have shown variable efficacy. Game theory is used to analyze population behaviour towards voluntary BCG vaccination policies. Such an approach allows quantifying how risk perception influences expected vaccine uptake and coverage levels. The threshold in perceived relative risk is computed from the basic reproduction, computed from a simplified mathematical model for the dynamics of tuberculosis with vaccination.
