Extension Study of H01_04TP to Evaluate the Booster Response Induced by Vi-CRM197 in Adults

Typhoid Fever Clinical Trial

Official title:
A Phase 2, Open-label, Single-center, Extension Study to Evaluate the Booster Response Induced by Vi-CRM197 After Priming With Either Vi-CRM197 or Typherix Administered in Adult Subjects in H01_04TP Study (NCT01193907)

Clinical Trial Summary

The purpose of this study is to evaluate the immunogenicity and the kinetics of the anti-Vi antibody response following secondary vaccination with the Novartis Vaccines Institute for Global Health (NVGH) Vi-CRM197 vaccine in healthy adults previously vaccinated with either the NVGH Vi-CRM197 or Vi-polysaccharide (Typherix) in the H01_04TP study (NCT01193907) and the immunogenicity and the kinetics of the anti-Vi antibody response following primary vaccination with the NVGH Vi-CRM197 vaccine in naïve healthy adults.
