Population: Per-protocol population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity). Here, "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

Seroconversion Rate (SCR) for each Outer Surface Protein A (OspA) serotype specific IgG ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12) and 545 (Month 18). Seroconversion for ELISA was defined as 1) for participants that are seronegative at Visit 1 (baseline): a change from seronegative at Visit 1 to seropositive at a certain time point or 2) for participants that are seropositive at Visit 1 (baseline): greater than or equal to (\>=) 4-fold rise in IgG antibody titer from Visit 1. SCR was reported as percentage of participants. Percentages are based on the number of participants with non-missing observations.

SECONDARY outcome

Timeframe: Day 29 (Month 1), Day 57 (Month 2), Day 85 (Month 3), Day 180 (Month 6), Day 208 (Month 7), Day 365 (Month 12) and Day 545 (Month 18)

Population: Per-protocol population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity). Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure and "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

SCR for IgG against each OspA serotype ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12) and 545 (Month 18) stratified by age group: 18 - 49 years. Seroconversion for ELISA was defined as 1) for participants that are seronegative at Visit 1 (baseline): a change from seronegative at Visit 1 to seropositive at a certain time point or 2) for participants that are seropositive at Visit 1 (baseline): \>=4-fold rise in IgG antibody titer from Visit 1. SCR was reported as percentage of participants.

Population: Booster PP population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity) and who were enrolled into the booster phase despite exclusion from the PP population of main study phase. Here, "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

SCR for each OspA serotype specific IgG ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12), 545 (Month 18), Month 19, Month 24, and Month 30. Seroconversion for ELISA was defined as 1) for participants that are seronegative at Visit 1 (baseline): a change from seronegative at Visit 1 to seropositive at a certain time point or 2) for participants that are seropositive at Visit 1 (baseline): greater than or equal to (\>=) 4-fold rise in IgG antibody titer from Visit 1. SCR was reported as percentage of participants. Percentages are based on the number of participants with non-missing observations. The outcome measure was planned to be analyzed for Booster PP population from Day 29 to Day 545 of main study phase and from day of vaccination in Month 18 up to Month 30 of booster phase.

SECONDARY outcome

Timeframe: Day 1 (baseline from where comparison was done), Day 29 (Month 1), Day 57 (Month 2), Day 85 (Month 3), Day 180 (Month 6), Day 208 (Month 7), Day 365 (Month 12), Day 545 (Month 18), Month 19, Month 24, and Month 30

Population: Booster PP population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity) and who were enrolled into the booster phase despite exclusion from the PP population of main study phase. Here, "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

GMFR as compared to baseline for IgG against each Osp serotype ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12), 545 (Month 18), Month 19, Month 24 and Month 30 were reported in this outcome measure. The outcome measure was planned to be analyzed for Booster PP population from Day 1 to Day 545 of main study phase and from day of vaccination in Month 18 up to Month 30 of booster phase.

SECONDARY outcome

Timeframe: Day 29 (Month 1), Day 57 (Month 2), Day 85 (Month 3), Day 180 (Month 6), Day 208 (Month 7), Day 365 (Month 12), Day 545 (Month 18), Month 19, Month 24, and Month 30

Population: Booster PP population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity) and who were enrolled into the booster phase despite exclusion from the PP population of main study phase. Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure and "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

SCR for IgG against each OspA serotype ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12), 545 (Month 18), Month 19, Month 24 and Month 30 stratified by age group: 18 - 49 years was presented in this outcome measure. Seroconversion for ELISA was defined as 1) for participants that are seronegative at Visit 1 (baseline): a change from seronegative at Visit 1 to seropositive at a certain time point or 2) for participants that are seropositive at Visit 1 (baseline): \>=4-fold rise in IgG antibody titer from Visit 1. SCR was reported as percentage of participants. The outcome measure was planned to be analyzed for Booster PP population from Day 29 to Day 545 of main study phase and from day of vaccination in Month 18 up to Month 30 of booster phase.

SECONDARY outcome

Timeframe: Day 29 (Month 1), Day 57 (Month 2), Day 85 (Month 3), Day 180 (Month 6), Day 208 (Month 7), Day 365 (Month 12), Day 545 (Month 18), Month 19, Month 24, and Month 30

Population: Booster PP population, excluded those participants with at least one relevant protocol deviation (i.e., a protocol deviation with possible impact on immunogenicity) and who were enrolled into the booster phase despite exclusion from the PP population of main study phase. Here, "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure and "Number Analyzed" signifies participants evaluable for this outcome measure at specified time points.

SCR for IgG against each OspA serotype ST1 to ST6, determined by ELISA, at Day 29 (Month 1), 57 (Month 2), 85 (Month 3), 180 (Month 6), 208 (Month 7), 365 (Month 12), 545 (Month 18), Month 19, Month 24, and Month 30 stratified by age group: 50 - 65 years. Seroconversion for ELISA was defined as 1) for participants that are seronegative at Visit 1 (baseline): a change from seronegative at Visit 1 to seropositive at a certain time point or 2) for participants that are seropositive at Visit 1 (baseline): \>=4-fold rise in IgG antibody titer from Visit 1. SCR was reported as percentage of participants. The outcome measure was planned to be analyzed for Booster PP population from Day 29 to Day 545 of main study phase and from day of vaccination in Month 18 up to Month 30 of booster phase.

SECONDARY outcome

Timeframe: From Day of vaccination in booster phase (Month 18) up to Month 30 (Approximately maximum up to 12 Months)

Population: Booster safety population included all participants who received the booster vaccination.

SAE was any untoward medical occurrence that at any dose resulted in any of the following outcomes or deemed significant for any other reason: death; required inpatient prolonged existing hospitalization; life-threatening; persistent or significant disability/incapacity; congenital anomaly/birth defect. Two-sided 95% confidence intervals were calculated according to Altman method.
