* Administration of immunoglobulins and/or any blood products within the three months preceding each persistence timepoint.
* Concurrently participating in another clinical study within 30 days of each persistence timepoint, in which the subject has been or will be exposed to an investigational or a non-investigational product (pharmaceutical product or device).
* Bleeding disorders, such as thrombocytopenia, or subjects on anti-coagulant therapy.
* Subjects withdrew consent to be contacted for follow-up studies.
Exclusion criteria for primary (naive control)/booster vaccination at year 5 study entry (to be checked at Year 5)

* Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the primary (naive control)/booster vaccination.

* Vaccination with meningococcal polysaccharide or conjugate vaccine outside of study with NCT number=00471081.
* History of any meningococcal disease.
* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history (no laboratory testing is required).

* Bleeding disorders, such as thrombocytopenia, or subjects on anti-coagulant therapy.
* Subjects withdrew consent to be contacted for follow-up studies.
* Hypersensitivity to latex.
* Previous administration or planned administration/ administration of a vaccine not foreseen by the study protocol during the period starting from 30 days of the study vaccination (primary vaccination for the naïve control group and booster vaccination for subjects primed in Study with NCT number = 00471081) and ending 30 days after with the exception of any licensed inactivated influenza vaccine (live attenuated influenza vaccine is not allowed).
* Previous administration or planned administration of tetanus or any tetanus containing vaccine during the period starting from 30 days of the study vaccination and ending 30 days after.

* History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
* Major congenital defects or serious chronic illness.
* History of any neurological disorders or seizures.
* Acute disease at the time of vaccination. (Acute disease is defined as the presence of a moderate or severe illness with or without fever. All vaccines can be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection with or without low-grade febrile illness, i.e., temperature by any method \< 99.5°F (37.5°C).
