IMDs assessed included among others neuroinflammatory disorders (such as optic neuritis, multiple sclerosis, or encephalitis), musculoskeletal disorders (such as cutaneous lupus, rheumatoid arthritis, juvenile arthritis, or psoriatic arthropathy), gastrointestinal disorders (ulcerative colitis and ulcerative proctitis, celiac disease), metabolic diseases (such as autoimmune thyroiditis, or diabetes Mellitus Type 1, Addison's disease), skin disorders (such as psoriasis or vitiligo), and other disorders such as vasculitis, pernicious anemia, or, sarcoidosis.
Number of Subjects With Unsolicited Adverse Events (AEs)
An unsolicited AE was defined as an untoward medical occurrence in a patient or clinical investigation subject, temporally associated with use of a medicinal product, whether or not considered related to the medicinal product) reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms.
Number of Subjects With Any and Fatal Serious Adverse Events (SAEs) Within the 30-day Follow-up Periods (Days 0-29)
A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or a reported adverse event of specific interest such as seizures occurring within a 30-day period of vaccination, immune-mediated disorders, and specific autoimmune diseases. A fatal SAE was defined as a SAE resulting in the death of the study subject.
Number of Subjects With Any and Fatal Serious Adverse Events (SAEs) From Day 0 to Month 8
A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or a reported adverse event of specific interest such as seizures occurring within a 30-day period of vaccination, immune-mediated disorders, and specific autoimmune diseases. A fatal SAE was defined as a SAE resulting in the death of the study subject.
Number of Subjects With Any and Fatal Serious Adverse Events (SAEs) From Day 0 to Month 26
A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or a reported adverse event of specific interest such as seizures occurring within a 30-day period of vaccination, immune-mediated disorders, and specific autoimmune diseases. A fatal SAE was defined as a SAE resulting in the death of the study subject.
Number of Subjects With Any, Fatal and Related Serious Adverse Events (SAEs) From Day 0 up to Study End (Month 51)
A serious adverse event (SAE) was defined as any untoward medical occurrence that resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity or a reported adverse event of specific interest such as seizures occurring within a 30-day period of vaccination, immune-mediated disorders, and specific autoimmune diseases. A fatal SAE was defined as a SAE resulting in the death of the study subject. A related SAE was defined as a SAE assessed by the investigator as being causally related to vaccination.

Use of a drug or vaccine that is not approved for that indication other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period. Administration of immunoglobulins and/or any blood products in the period between birth and Dose 1 and within the three months preceding planned vaccine administration during the study period. Chronic administration of immunosuppressants or other immune-modifying drugs in the period between birth and Dose 1. Concurrently participating in another clinical study at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational product. Same sex twin Maternal death History of allergic reactions or anaphylaxis to previous immunizations. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
