The pathogenesis of bacteraemia for human restricted pathogens such as Streptococcus pneumoniae, Haemophilus influenzae type b and Salmonella enterica serovar Typhi (ST), have thus far only been investigated in imperfect animal models. The Salmonella Typhimurium mouse model is widely employed
Description of the Research Project: It has been previously shown that IFN-gamma and IL-17 are increased in typhoid fever patients. It was shown that S. Typhi infection induces antibody responses against a number of key typhoid antigens (LPS) HlyE, Flagellar protein FliC and chaperon protein EcpD).
This study will be divided into two cohorts, by age, with separate study designs. The first cohort will include children 9 through 11 months of age. The second cohort will comprise children 15 through 23 months of age. The purpose of this detailed evaluation of safety and immunogenicity is to assess
A new generation of typhoid conjugate vaccines (TCVs) have been shown to be safe and provide long-lasting immunity in children. In India, Typbar TCV Vi-TT (Vi capsular polysaccharide conjugated with tetanus toxoid protein) is manufactured by Bharat Biotech International Limited (BBIL).
This study is a double-blind, individually randomized, controlled, clinical efficacy trial with two vaccine groups: Vi-TCV (Typhoid conjugate) and MCV-A (meningococcal group A conjugate). This study will take place in Blantyre, Malawi, Africa. Participants (up to 24,000) will be randomized in a 1:1
