Study: NCT02814708

Intervention type: BIOLOGICAL
Group type: EXPERIMENTAL
Intervention: rTSST-1v
Description: Each subject of a total of seven groups will receive three injections (first injection day 0; second injection 3 months ± 4 weeks after the first, third injection 6 months ± 4 weeks after the second) of one of two different doses of Vaccine or Adjuvant, each group comprising 20 subjects. Subjects will be controlled 24 h post vaccination. Follow-up will last 18 months on the average, with visits every three months (± 2 weeks). Response to treatment is defined by seroconversion from a TSST-1 binding Ab titer of \< 20 to \> 40 or a 4-fold increase in TSST-1 binding Ab titer .
