Summary: A cluster-randomised controlled Phase IV trial (cRCT) assessing the impact of a Vi-Polysaccharide conjugate vaccine in preventing typhoid infection in Asante Akim, Ghana (TyVEGHA) with a primary endpoint of determining the total protection conferred by single-dose vaccination with Vi-TT against blood culture-confirmed symptomatic S. Typhi infection in the intervention vaccine clusters, compared wi...
Summary: With this study the researchers aim to provide observational data on the treatment efficacy of currently used antibiotic treatment regimens for NTS BSI in hospital-admitted children. The study is an observational cohort study where the antibiotic treatments used and treatment outcomes in the St. Luc general referral hospital in Kisantu health zone (Province Kongo Central, DR Congo) will be describ...
Summary: Vi-DT Typhoid vaccine is a novel vaccine. This study will be done to know the long-term protection and persistent antibody by measured the antibody titer after 2,3,4 and 5 years after immunization.
Summary: At least 1.8 billion people globally use a source of drinking water that is faecally contaminated and thus likely to lead to diarrheal illness: nearly 1,000 children die each day due to water and sanitation-related diarrhoeal diseases. Diseases related to the consumption of contaminated drinking-water place a major burden on human health. In 2017, 785 million people still lacked access to an impro...

Summary: The study consists of two arms: 1) intervention group using eggs as supplementary food given from 2nd trimester of pregnancy to birth, and 2) observational group of pregnant mothers. it aims to assess the effectiveness of improving dietary quality during pregnancy on the epigenetic and stunting related outcomes (growth and development) in infants, who will be followed up until 24 months old
Summary: Bloodstream infections are frequent in children admitted to the hospital for severe febrile illness in sub-Saharan Africa.Ongoing blood culture surveillance at Kisantu Hospital showed non-typhoidal Salmonella (NTS) as the first cause of bloodstream infections in children. Bloodstream infections have a high case fatality (15 - 20%). Outcome of bloodstream infections is dependent on timely diagnosis...
Summary: Typhoid fever (typhoid) is an enteric bacterial infection caused by Salmonella enterica serovar Typhi (Salmonella Typhi; S. Typhi). It is one of the most common bacterial causes of acute febrile illness in the developing world, with an estimated 10.9 million new cases worldwide and 116.8 thousand deaths in 2017. Like many febrile illnesses, typhoid presents with non-specific symptoms and signs, es...
Summary: This is an open-label, non-randomized study. The purpose of this study is to better understand how vaccines against typhoid fever and cholera affect the normal immune system and bacteria in the intestine. Patients having standard-of-care endoscopies (colonoscopy and/or esophagogastroduodenoscopy (EGD)) will be divided into 3 groups:~Group 1: Vivotif typhoid vaccination and/or Vaxchora cholera vacc...
Summary: Typhoid fever caused by Salmonella Typhi and Paratyphi causes over 21 million cases of febrile illness and 200,000 deaths are attributed to enteric fever each year. Typhoid fever is an enteric infection that results in febrile illness. Typhoid fever causes significant morbidity in the developing world especially young children.S. Typhi specific antibody responses are elicited in typhoid fever and ...
Summary: Bladder cancer is the fourth and eighth most common malignancy among men and women, respectively. About 75% of bladder cancers are diagnosed as non muscle-invasive and according to specific tumor-stage and grade characteristics, intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) is used to prevent recurrence and/or progression. However, BCG immunotherapy is associated with significant ...
Summary: This is a controlled cohort study to assess the effect of improved sanitation on oral rotavirus vaccine performance in low-income urban neighbourhoods of Maputo, Mozambique. The specific hypotheses are that: (1) access to improved sanitation is associated with increased oral rotavirus vaccine immunogenicity; (2) enteric infection concurrent to oral rotavirus vaccination is associated with reduced ...
