Article Abstract
There are some concerns about the safety of live attenuated yellow fever vaccines (YF-live), particularly viscerotropic adverse events, which have a high mortality rate. The cellular production of the vaccine will not cause these adverse effects and has the potential to extend applicability to those who have allergic reactions, immunosuppression, and age. In this study, inactivated yellow fever (YF) was prepared and adsorbed with Alum/CpG. The cellular and humoral immunities were investigated in a mouse model. The results showed that Alum/CpG (20 μg/mL) could significantly increase the binding and neutralizing activities of the antibodies against YF. Moreover, the antibody level at day 28 after one dose was similar to that of the attenuated vaccine, but significantly higher after two doses. At the same time, Alum/CpG significantly increased the levels of IFN-γ and IL-4 cytokines.

Background: Yellow fever virus (YFV) remains a re-emerging zoonotic threat in South America. While epizootics in free-ranging spp. are well-documented, little is known about YFV infection in other Neotropical non-human primates (NHPs), particularly in captive settings.

Excessive use of agrochemicals results in contamination of water due to runoff or leaching. Insecticide induced-hormesis, a phenomenon characterized by low dose stimulation following exposure to insecticide, is crucial to insect pest resurgence. In this study, the effects of low or sublethal concentrations of emamectin benzoate and thiamethoxam on biological traits and genes expression were investigated for yellow fever mosquito, Aedes aegypti following 48 h exposures.

Widespread yellow fever virus (YFV) immunity in Sub-Saharan Africa may mitigate orthoflavivirus outbreaks. Here, we investigate whether pre-existing YFV-17D immunity confers cross-protection against dengue virus serotype 2 (DENV-2) infection in a murine model. IFNAR1 mice immunized with YFV-17D exhibited significantly reduced DENV-2 viremia, weight loss, and disease severity, with improved survival compared to naïve controls.

Background: The genus primarily consists of arthropod-borne viruses capable of infecting vertebrate hosts and causing serious human diseases such as dengue fever, Zika fever, Japanese encephalitis, West Nile fever, and yellow fever. This study describes the development of a simple and field-deployable detection system for multiple pathogenic orthoflavivirus species using the recombinase polymerase amplification (RPA) technique.
Methods: Several previously published broad-specific primers targeting the genus were evaluated.
