Figure 7.

In this figure we plot the quasi-instantaneous reproduction number with vaccination $R_V^0\left(t\right)=\frac{\tau \left(t\right)W\left(t\right)S_0}{\eta \nu }\times (\eta +\kappa \nu (1-f))$. The blue background color regions correspond to epidemic phases, and the yellow background color regions to endemic phases.
