Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Pooled 20vPnC | Participants were randomized to receive a single 0.5 mL intramuscular injection of 20vPnC from any of the lots 1, 2 or 3 on Day 1. Participants were followed up to 6 months after vaccination. | 0 | 1,463 | EG000 |
| Group 2 | 13vPnC | Participants were randomized to receive a single 0.5 mL intramuscular injection of 13-valent pneumococcal vaccine (13vPnC) on Day 1. Participants were followed up to 6 months after vaccination. | 0 | 245 | EG001 |
