OBJECTIVE Conjugate vaccines are the best public health tools available for preventing most invasive diseases caused by Haemophilus influenzae type b (Hib), but the high cost of the vaccines has so far kept them from being introduced worldwide. The objective of this study was to estimate the cost-effectiveness of introducing Hib conjugate vaccines for the prevention of meningitis and pneumonia among children under 2 years of age in Colombia. METHODS We estimated the direct and indirect costs of managing in-hospital pneumonia and meningitis cases. In addition, following the recommendations of the World Health Organization, we assessed the cost-effectiveness of Hib vaccination programs. We also estimated the costs for preventing Hib cases, and the cost per year of life saved in two hypothetical situations: (1) with vaccination against Hib (with 90% coverage) and (2) without vaccination. RESULTS The average in-hospital treatment costs were 611.50 US

per year of life saved without vaccination. CONCLUSION Having an adequate Hib vaccination program in Colombia could prevent around 25,000 cases of invasive disease per year, representing a cost savings of at least 15 million US

annually. Furthermore, the program could prevent some 700 deaths per year and save 44,054 years of life per year.OBJETIVOS: Las vacunas conjugadas contra Haemophilus influenzae tipo b (Hib) son la herramienta mas importante para prevenir la mayoria de las enfermedades invasoras producidas por dicho patogeno, pero debido a su costo, aun no se han introducido mundialmente de manera masiva. En el presente estudio se determino la relacion costo-efectividad de una vacuna contra Hib para prevenir la neumonia y la meningitis bacterianas en ninos menores de 2 anos en Colombia. METODOS: Se estimaron los costos directos e indirectos de la neumonia y la meningitis hospitalaria y siguiendo las recomendaciones de la Organizacion Mundial de la Salud (OMS), la relacion costo-efectividad de los programas de vacunacion contra Hib. Se estimaron tambien las razones de costos por caso evitado de enfermedad invasora por Hib y el costo por ano de vida salvado en dos situaciones hipoteticas: con vacunacion contra Hib (cobertura vacunal: 90%) y sin vacunacion. RESULTADOS: El costo medio del tratamiento hospitalario de un caso de neumonia fue de 611,5 dolares estadounidenses (US
