Beskrivelse
Inclusion Criteria:
All subjects must satisfy ALL the following criteria at study entry:
- Subjects' parent(s)/Legally Acceptable Representative(s) [LAR(s)] who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
- A male or female who has received primary and booster vaccination with the MenACWY-TT or Meningitec vaccines in studies MENACWY-TT-039 (109670) and MENACWY-TT-048 EXT: 039 Y2, 3, 4, 5 (112036), respectively.
- Written informed consent obtained from the parent(s)/LAR(s) of the subject.
- Healthy subjects as established by medical history and clinical examination before entering into the study.
Exclusion Criteria:
The following criteria should be checked at the time of study entry. If ANY exclusion criterion applies, the subject must not be included in the study:
- Child in care.
- History of meningococcal disease.
- Administration of a meningococcal polysaccharide or a meningococcal polysaccharide conjugate vaccine outside of studies MENACWY-TT-039 (109670) and MENACWY-TT-048 EXT: 039 Y2, 3, 4, 5 (112036).
- Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
- Bleeding disorders, such as thrombocytopenia, or subjects on anti-coagulant therapy.

Number of Participants With Treatment Emergent Serious Adverse Events (SAEs)
Tidsramme: Baseline up to the Month 72 after booster vaccination (up to 6 years)
|
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Treatment-emergent are events between first dose of study drug and up to 72 months after last dose of study drug that were absent before treatment or that worsened relative to pretreatment state.
