); in the context of climatic change, an unclear knowledge about the immune behaviour of the virus, between other determinants. This review details the historical foundations, intricate evolution of geographical spread, and transmission mechanisms of the disease to understand the behaviour of outbreaks over time in a multifactorial context that could be difficult to understand. This article approaches to epidemiological, pathophysiological, immunological, social determinants, and climatic crisis by understanding possible control mechanisms and anticipating potential future epidemics. This article explores the evidence of yellow fever virus (YFV) pathogenesis and its complex interactions with the immune response in the host, the vector, and in the context of immunisation. These discussions contribute to a more comprehensive understanding of the disease's progression. Despite the global presence of the vector and other factors that could facilitate an epidemic spread, yellow fever outbreaks have remained confined to specific endemic areas. This limited distribution is not entirely understood. However, it may be influenced by the complex immune interactions between the virus, the vector, and the host, preventing its spread to other regions.
