This document presents a mathematical model that examines the effects of vaccination against tuberculosis transmission from mother to child. The model divides the population into five groups: those immunized by the BCG vaccine, susceptible individuals, those with mild infection, those with severe infection, and recovered individuals. The model equations describe the transitions between these groups over time based on factors like natural death rate, infection rates, recovery rates, and vaccine efficacy expiration. Analysis of the model finds disease-free and endemic equilibrium states. Stability analysis determines that the endemic equilibrium will be stable if the total removal rate from the infectious class is greater than the number of latent infections produced during the infectious period. In other words, vaccination must reduce the basic reproduction number R0 to
