Meningococcal infection

This study will monitor the safety of the MenQuadfi vaccine in 706 people aged 6 weeks to 55 years in South Korea. Researchers will track side effects like injection-site reactions and serious adverse events as the vaccine is used in real-world clinics. The goal is to confirm the…

This Phase 3 trial tests a new vaccine designed to protect infants aged 3 to 5 months against four strains of meningococcal bacteria that cause meningitis and sepsis. About 880 healthy babies will receive either the experimental vaccine or a licensed comparator vaccine. Researche…

This Phase 3 trial tests a new meningococcal conjugate vaccine in 660 healthy children aged 2-6 years. The vaccine targets four strains (A, C, Y, W135) that cause meningitis. Participants receive one shot and provide blood samples to compare immune response with a licensed vaccin…

This study tests a new vaccine to protect young children (12-23 months old) against four types of meningococcal bacteria that can cause meningitis. About 1,040 toddlers will receive either the new vaccine or an existing one to see if the new vaccine is as safe and effective. The …

This Phase 3 trial tests a new vaccine against four types of meningococcal bacteria (A, C, Y, W135) that cause meningitis. About 1,040 healthy infants aged 6 to 11 months will receive either the experimental vaccine or a licensed comparator. Researchers will measure immune respon…

This early-stage trial is testing a new vaccine designed to protect against several types of meningococcal bacteria, which can cause meningitis and bloodstream infections. Researchers will enroll 150 healthy people aged 2 to 59 to check the vaccine's safety and how well it trigge…

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 will recruit 100 sexual partners of people diagnosed with gonorrhea. Researchers will take an extra throat swab to analyze all the bacteria and their genes using a technique called metagenomics. The goal is to find hidden infections, antibiotic resistance, and see how …

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 early-stage study will give a single dose of the experimental antibiotic gepotidacin to 20 hospitalized children aged 2 to 12 who are already receiving standard antibiotics for a bacterial infection or as a preventive measure. Researchers will measure how the drug moves thro…

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…
