This study tests a new vaccine (IP-QSV) designed to protect against four types of Shigella bacteria, which cause severe diarrhea. The trial will include 370 healthy adults, children, and infants in Mali. Researchers will check if the vaccine is safe and triggers a strong immune r…

This early-stage study tests a new oral cholera vaccine called DuoChol in 60 healthy adults aged 18 to 45 in Sweden. Participants will receive two doses of either DuoChol or an existing vaccine (Dukoral) to compare safety and immune response. The goal is to gather initial data to…

This study follows up on African children who received an experimental Shigella vaccine in earlier studies. Researchers will take blood samples 1, 2, and 3 years after the last vaccine dose to see how long the immune protection lasts. No new vaccines are given in this study. The …

This study compares two common antibiotic combinations—vancomycin with piperacillin/tazobactam versus vancomycin with meropenem—to see which is less harmful to the kidneys. About 852 hospitalized adults with serious infections will be randomly assigned to one of the two combos. T…

This study tests whether adding a probiotic called Lacticaseibacillus rhamnosus GG to standard care (like rehydration fluids) can shorten the duration of acute infectious diarrhea in children. About 480 kids aged 1 month to 10 years in Turkey will take part. Half will get the pro…

This study looks at whether a special oral nutritional supplement, combined with dietary counseling, can improve growth in children who are not growing as expected. About 216 children will be randomly assigned to receive either the supplement plus counseling or counseling alone. …

This observational study will look at 10,000 adults in intensive care units (ICUs) around the world during a single 24-hour period. Researchers want to find out how common infections and antibiotic-resistant bacteria are, how they are treated, and how patients recover. No new tre…

This research project aims to understand why older adults get more infections and why those infections can be more serious. By following 23,000 people aged 60 and older, scientists will collect health data and samples like blood and stool to study how the immune system changes wi…

This pilot study will test a mobile app called ADEPT among 30 village doctors in Bangladesh. The app helps doctors decide when antibiotics are truly needed for children with diarrhea. The goal is to see if using the app reduces unnecessary antibiotic prescriptions, which is a maj…

This study will collect blood samples from 30,000 adults in the UK with various health conditions, including blood clots, infections, heart disease, diabetes, and more. The samples will be used to develop and fine-tune new diagnostic tests for the cobas® lumira device, which allo…

This study will follow 300 adults with severe infections in the ICU to see how levels of specialized pro-resolving mediators (SPMs)—natural molecules that help stop inflammation—change over time. Researchers will use blood samples already collected during routine care, so no extr…

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By meas…
