Condition
Meningococcus B disease
Intervention
Randomised open-label study with four arms:
1. Men-B-Bio 12.5 µg
2. Men-B-Bio 25 µg
3. Men-B-Bio 50 µg
4. Similar Cuban vaccine (reference vaccine)
At the end of the study we expect to choose the best dose for the Brazilian vaccine.
Total duration: 20 months
Total duration of follow up: 20 months
Blood samples: before 1st dose, before 3rd dose and 1 month after 3rd dose
The second (25 µg) and third (50 µg) concentration groups will start after completion of the first concentration (12.5 µg) evaluation, hence the extension of the study to 20 months of follow up.
