This is my code for a math bio project.
For this project, I looked at COVID vaccination rate, immunity loss, vaccination probability fluctuation, and two populations interacting with each other using an SIR model. I expanded on the SIR model presented in Widyaningsih et al. (2018).
Here are the parameters:
Here is the overall model:
Referece: Widyaningsih et al. "Susceptible infected recovered model with vaccination, immunity loss, and relapse to study tuberculosis transmission in Indonesia." (2018).
