This early-stage trial is testing a new vaccine called HydroVax-001B WNV to see if it is safe and triggers an immune response against West Nile virus, a mosquito-borne disease. About 30 healthy adults aged 18 to 49 will receive either the vaccine or a placebo. The study will comp…

This Phase 2 trial tests a new vaccine called MVA-BN-WEV to prevent two types of equine encephalitis (Eastern and Venezuelan), which are rare but serious brain infections spread by mosquitoes. The study involves 411 healthy adults aged 18-50 and aims to find the best dose and dos…

This trial tests different vaccination schedules for Japanese encephalitis in healthy children starting at 8 months old. Researchers compare how well each schedule triggers and maintains protective antibodies through age 6, including the effect of booster doses. The study also mo…

This study looks at how the immune system of patients in the intensive care unit (ICU) responds to severe infections caused by viruses or bacteria. Researchers will take extra blood samples from 38 adults to analyze immature granulocytes, a type of immune cell. The goal is to see…
