Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Safety data in both groups, as assessed by the frequency, incidence, and nature of adverse events (AEs) and serious adverse events (SAEs) during the study. Safety is measured throughout the one year follow up period, but specifically on the following days: 2, 7, 14, 28, 56, 84, 168 and 364. Blood for safety testing is taken at Days 7 and 28. | — |
Secondary
| Measure | Time frame |
|---|---|
| Immunogenicity data in both groups. This will be obtained from exploratory immunological laboratory investigations on blood samples taken at screening, and throughout follow up. Immunogenicity is measured throughout the one year follow up period, but specifically on the following days: 2, 7, 14, 28, 56, 84, 168 and 364. | — |
