The effects on mortality presented by vaccines, especially BCG, which presents the strongest evidence, due to randomized studies carried out in Guinea-Bissau; It seems to encompass not only direct protection, but apparently generates a good heterogeneous adaptive immune response. A systematic review was carried out, with the objective to analyze the behavior of the infant mortality rate after timely immunization, through the consultation of scientific articles in different reliable databases with the application of DeCS and MeSH. The collection of articles was systematic, for which the PRISMA declaration was used. The authors mostly agreed that timely immunization produces a decrease in the infant mortality rate, especially in low-resource countries where the risk of contracting any of these pathologies is greater. However, one of the studies carried out in the United States showed an increase in the infant fatality rate when a greater number of doses is applied. Concluding that vaccines turned out to be effective in reducing the infant mortality rate, particularly in low-income territories.
