Resumen

Introducción: Este estudio examina la evolución de los marcos temáticos en la cobertura mediática mexicana sobre las vacunas contra la COVID-19 entre 2020 y 2021, dado que las narrativas de los medios configuran la percepción pública y la confianza institucional durante crisis sanitarias. Objetivos: La investigación busca identificar y analizar los temas dominantes en la cobertura de vacunas contra la COVID-19 en México y seguir su evolución temporal. Metodología: Se analizó un corpus de 43.358 artículos de periódicos nacionales relevantes en México. Utilizando Latent Dirichlet Allocation (LDA), una técnica de modelado de temas del Procesamiento de Lenguaje Natural, se categorizó trimestralmente el contenido de las noticias para mapear la evolución temática a lo largo del tiempo. Resultados: Se identificaron cinco temas principales: crisis sanitaria y económica global, relaciones internacionales, gestión de la pandemia a nivel estatal, respuestas institucionales a grupos sociales y política nacional de salud pública. Los hallazgos muestran una progresión clara desde marcos centrados en la crisis global hacia discusiones de política más localizadas. Conclusión: El estudio destaca cómo la cobertura mediática evoluciona en respuesta a cambios sociales y epidemiológicos, ofreciendo información valiosa para el diseño de estrategias de comunicación sanitaria oportunas y culturalmente apropiadas.
