简要总结
The purpose of this study is to evaluate the safety, reactogenicity, and immune response of the GlaxoSmithKline (GSK) Vaccines Institute for Global Health (GVGH) invasive nontyphoidal Salmonella-generalized modules for membrane antigens (iNTS-GMMA) candidate vaccine against S. Typhimurium and S. Enteritidis with an age de-escalation and dose escalation approach in African population, starting with adults (18-50 years of age), then in children (24-59 months of age) and finally in infants (9 months and 6 weeks of age). Infants are the target for primary vaccination from 6 weeks of age.
详细描述
The study will be conducted as follows:
- Adult participants will receive either iNTS-GMMA Dose C (high) or a control vaccine intramuscularly on Day 1 and Day 57.
- Child participants will receive either Dose B (medium) or Dose C (high) of the candidate vaccine or the control on Day 1 and Day 57.
- Infant participants (9 months of age) will receive either Dose A (low), Dose B (medium), or Dose C (high) of the candidate vaccine or the control on Day 1, Day 85, and Day 169.
- Infant participants (6 weeks of age) will receive either Dose A (low), Dose B (medium), or Dose C (high) of the candidate vaccine or the control on Day 1, Day 57 and Day 232.
