Impact of Malaria Vaccination on Malaria Infection inCôte d’Ivoire: Mathematical Modeling of MalariaCases in The Context of Childhood Vaccination

In Côte d’Ivoire, a malaria routine vaccination targeting a specific age group of children began in 2024. In this article, we propose a mathematical model of malaria cases by age group that takes this vaccination into account; this model will allow us to study the impact of this vaccination on malaria dynamics in Côte d’Ivoire. We have shown that it is very costly to reach a disease-free equilibrium and have also determined the ‎basic reproduction number for such an equilibrium. However, we have observed that the vaccination coverage rate strongly influences malaria ‎dynamics. Graphical analysis and numerical simulations corroborate these results. This mathematical model allows us to make predictions that will be ‎important for decision-making and planning‎.
