| Arm | Type | Description |
|---|---|---|
| ACWY-TT group | EXPERIMENTAL | Subjects primed and boosted with the MenACWY-TT vaccine. |
| MenCCRM group | ACTIVE_COMPARATOR | Subjects primed and boosted with the Meningitec vaccine. |
| Arm 1 | EXPERIMENTAL | Includes subjects from a trial involving experimental vaccine and an active comparator vaccine. Comparator is Twinrix (not a MnB vaccine) and thus is comparator for safety but not immunogencity |

Blood Sampling is an investigational clinical study procedure used in trials evaluating immune responses in healthy volunteers and in the context of meningococcal infections. It is not a therapeutic drug but a sampling method employed to measure antibody persistence and duration of immunity following vaccination.
Blood Sampling is being developed by Pfizer, Inc. (NYSE: PFE). The company sponsors clinical trials that utilize blood sampling to assess immune responses, including studies of meningococcal vaccines in healthy children and adults.
Blood Sampling is associated with clinical trials in Phase 1 and Phase 3. One completed Phase 1 study evaluated duration of immunity in healthy adults, and a completed Phase 3 study assessed antibody persistence in healthy children after meningococcal vaccination.
Blood Sampling is used in two completed trials: NCT00518492, a Phase 1 study in healthy adults in Australia evaluating duration of immunity, and NCT01900899, a Phase 3 study in healthy children in Finland assessing antibody persistence after meningococcal vaccine PF-06866681.
No, Blood Sampling is not a vaccine. It is a clinical procedure for collecting blood samples to measure immune markers such as antibody levels. In the trials listed, it is used to evaluate responses to meningococcal vaccines, not as an intervention itself.
