About This Trial

The goal of this observational study is to learn about the impact of malaria vaccination on the risk of invasive non-typhoidal Salmonella disease in children below the age of 5. Eligible participants residing in the Kisantu Health Zone (DRC) and presenting fever are enrolled in healthcare facilities and tested for malaria and iNTS. Using a case-control (test-negative) design, the researchers will look at the malaria vaccination status of participants with and without iNTS infection to determine if the malaria vaccine protects against iNTS.
