Brief Summary

This study is designed to assess the immunogenicity and safety of typhoid Vi polysaccharide vaccine in Japanese participants to support registration of the product in Japan.

Primary Objective:

To describe the seroconversion rate (percentage of subjects with at least a 4-fold increase of their Vi antibody titer) between Day 0 before vaccination and Day 28 after vaccination with typhoid Vi polysaccharide (SP093) vaccine in subjects aged 2 years and above.

Secondary Objectives:

• To describe the safety profile of a single dose of typhoid Vi polysaccharide vaccine up to 28 days after vaccination, in subjects aged 2 years and above.
• To describe the immune response following a single dose of typhoid Vi polysaccharide vaccine in subjects aged 2 years and above.

Detailed Description

All participants will receive a single dose of typhoid Vi polysaccharide vaccine on Day 0 and be assessed for immunogenicity on Day 0 before vaccination and on Day 28 post-vaccination. All participants will be monitored for safety for up to 28 days post-vaccination.

Conditions

Salmonella Infections; Typhoid Fever; Bacterial Infections
