Abstract: | Two models are presented which can show a backward bifurcation. The possibilities are analyzed whether latency, quarantine, vaccine efficacy, and other parameters of the models can affect the appearance of a backward bifurcation. Explicit conditions on the parameters are given for the backward bifurcation to be present, to be reduced, or to disappear. |
