\item Some backgrounds may have restricted access to mosquito resistant materials  \item Some backgrounds may have a lower propensity to be vaccinated.  \end{enumerate}  It is very different to try to quantify these factors and then adapt the basis model accordingly. There is however one other major factor that can be quantified. The basis SIR model naturally assumes that the transmission of the disease occurs between humans. However, this not the case for yellow fever. The virus is transmitted by the (FILL ME!) mosquito only (CORRECT ME!). It therefore makes the makes the parameters used in the SIR model, such as $\beta$ irrelevant, and will of course cause the model to be inaccurate. inaccurate., as well as calculations involving $\beta$, such as $R_0$ wrong.
