International audience ; The purpose of this study is to build an epidemic model with vaccination control for Covid-19 in El Salvador. A combination of epidemiological SEIR (Susceptible, Exposed, Infectious or Recovered) models and the estimation of parameters using machine learning and contact networks is proposed. The project consisted of three phases: a) Analysis: the critical or key factors or variables of the phenomenon under study were identified, the model to be used, as well as its parameters and components, were defined, designed, and constructed b) Simulation: simulation made it possible to modify variables, implement alternatives, and modify the model itself without affecting the real system, which is highly useful for decision-making and preparing results and recommendations. The simulations were carried out using population data from El Salvador. c) Optimization: different scenarios were evaluated in which vaccination control measures and social distancing measures were applied, in order to identify the optimal strategy. As a result of this study, the best strategy for controlling the disease was identified: a combination of vaccinating the vulnerable population and maintaining social distancing measures provided the best results in terms of reducing the impact of infection and minimizing treatment costs. Finally, recommendations are made to government health authorities for distribution and application of the treatment. ; Este estudio tiene como objetivo general construir un modelo epidémico con control por vacunación para el Covid-19 en El Salvador. Se propone la combinación de modelos epidemiológicos SEIR (Susceptibles, Expuestos, Infectados o Recuperados) y la estimación de parámetros usando machine learning y redes de contacto. El proyecto se desarrolló siguiendo tres fases: a) Análisis: se realizó la identificación de factores o variables críticas o claves del fenómeno en estudio, se definió, diseñó y construyó el modelo a utilizar junto con sus parámetros y componentes. b) Simulación: una vez ...
