A suspected case of HZ is defined as new unilateral rash accompanied by pain (broadly defined to include allodynia, pruritus or other sensations) and no alternative diagnosis. A suspected case of HZ can be confirmed in two ways: * By PCR; * By the HZ Ascertainment Committee (HZAC).
A participant with vaccine response for anti-gE was defined as a participant with: * at least a 4-fold greater post-last vaccination anti-gE antibody (Ab) concentration as compared to the pre-vaccination anti-gE Ab concentration, for participants who were seropositive at baseline, or * at least a 4-fold greater post-last vaccination anti-gE Ab concentration as compared to the anti-gE Ab cut-off value for seropositivity, for participants who were seronegative at baseline.
Anti-gE antibody concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and expressed as GMCs in milli-international units per milliliter (mIU/mL).
Anti-S antibody concentrations were determined by Multiplex Electrochemiluminescence assay and expressed as GMCs in arbitrary units per milliliter (AU/mL).
Antibody titers against the 4 influenza strains (A/H1N1 strain, A/H3N2 strain, B/Victoria lineage and B/Yamagata lineage) included in the FLU D-QIV vaccine were determined by hemagglutination inhibition and expressed as GMTs.
Anti-S antibody concentrations were determined by Multiplex Electrochemiluminescence assay and expressed as GMCs in AU/mL.
Anti-gE antibody concentrations were determined by enzyme-linked immunosorbent assay (ELISA) and expressed as geometric mean concentrations (GMCs) in milli-international units per milliliter (mIU/mL).
Anti-gE antibody concentrations were determined by ELISA and expressed as GMCs in mIU/mL.
Vaccine response rate (VRR) for Varicella Zoster Virus (VZV) anti-glycoprotein E (gE) humoral immunogenicity was determined by Enzyme Limked Immunosorbent Assay (ELISA). The VRR for anti-gE is defined as the percentage of subjects who had at least: a 4-fold increase in the anti-gE antibodies concentration as compared to the pre-vaccination anti-gE antibodies concentration, for subjects who are seropositive at baseline, or, a 4-fold increase in the anti-gE antibodies concentration as compared to the anti-gE antibodies cut-off value for seropositivity, for subjects who are seronegative at baseline.
Anti-gE antibody concentrations in terms of Geometric Mean concentrations (GMC) were determined by ELISA and expressed as milli-international units per milliliter (mIU/mL)
Anti-pneumococcal antibody titers for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) were determined by Multiplex Opsonophagocytosis Assay (MOPA)
Anti-gE antibody concentrations (GMCs) adjusted for age and baseline concentrations were determined using Analysis Of Covariance (ANCOVA) model. Adjusted GMCs were expressed in milli-international units per milliliter (mIU/mL)
Geometric mean antibody (anti-pneumococcal antibodies: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) titers adjusted for age and baseline concentration were determined using ANCOVA model.

| LTFU Group | OTHER | Participants who received at least one dose of the HZ/su vaccine in the ZOSTER-006/022 primary studies and are followed for long-term vaccine efficacy and safety in the current ZOSTER-101 study. |
| 1-Additional Dose Group | OTHER | Participants who received two doses of the HZ/su vaccine in the ZOSTER-006/022 primary studies and one additional dose of the HZ/su vaccine in the ZOSTER-049 study and are followed for persistence of immunogenicity and safety in the current ZOSTER-101 study. |
