Outcomes

Primary Outcome Measures

ELISA GMT
Geometric Mean Titers (GMT) based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Titers below the detection limit are included with a value of '1'

Secondary Outcome Measures

Number of Participants With Serious Adverse Events
Occurrence, relationship to the trial vaccine and intensity of any Serious Adverse Event (SAE).
Number of Participants With Adverse Events of Special Interest (AESI)
Occurrence, relationship to the trial vaccine and intensity of any Adverse Event of Special Interest (AESI). AESIs were defined as any cardiac symptoms and ECG changes determined to be clinically significant or cardiac enzyme troponin I elevated above 2 x the Upper Limit of Normal
Number of Participants With Related Grade >=3 Adverse Events
Occurrence of any Grade >=3 Adverse Events related to the trial vaccine.
Number of Participants With Unsolicited Adverse Events
Occurrence, relationship to the trial vaccine and intensity of unsolicited treatment-emergent AEs (TEAEs).
Number of Participants With Solicited Local Averse Events
Occurrence and intensity of solicited local AEs (redness, swelling, induration, pruritus and pain) during the 8-day period (day of vaccination and the following 7 days) after any vaccination. Events were graded by intensity (1 = mild, 2 = moderate, 3 = severe).
Number of Participants With Solicited General Adverse Events
Occurrence, intensity and relationship to the trial vaccines of solicited general AEs (pyrexia, headache, myalgia, nausea, fatigue and chills) during the 8-day period (day of vaccination and the following 7 days) after any vaccination. Events were graded by intensity (1 = mild, 2 = moderate, 3 = severe).
ELISA GMTs
Geometric Mean Titers (GMT) at all immunogenicity sampling time points based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). For the calculation of GMTs all measurements are included as they provide meaningful information even if below the detection limit (DL). Disregarding these measurements would highly bias the reported GMTs. We imputed values <DL as a value of '1' and the GMT and corresponding 95% confidence intervals were calculated.
PRNT GMT
Geometric Mean Titers (GMT) based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). Titers below the detection limit are included with a value of '1'
PRNT GMTs
Geometric Mean Titers (GMT) at all immunogenicity sampling time points based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). For the calculation of GMTs all measurements are included as they provide meaningful information even if below the detection limit (DL). Disregarding these measurements would highly bias the reported GMTs. We imputed values <DL as a value of '1' and the GMT and corresponding 95% confidence intervals were calculated.
Percentage of Participants With Seroconversion by ELISA
Seroconversion rate based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (50) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects.
Percentage of Participants With Seroconversion by ELISA
Seroconversion rates at all post-baseline immunogenicity sampling time points based on vaccinia-specific Enzyme-linked Immunosorbent Assay (ELISA). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (50) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects. Percentages based on number of subjects with data available.
Percentage of Participants With Seroconversion by PRNT
Seroconversion rate based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (2) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects.
Percentage of Participants With Seroconversion by PRNT
Seroconversion rates at all post-baseline immunogenicity sampling time points based on vaccinia-specific Plaque Reduction Neutralization Test (PRNT). Seroconversion is defined as the appearance of antibody titers ≥ detection limit (2) for initially seronegative subjects, or a doubling or more of the antibody titer compared to Baseline titer for initially seropositive subjects. Percentages based on number of subjects with data available.
ELISPOT Magnitudes of Response
Magnitudes of response of IFNγ producing T-cells measured by vaccinica-specific ELISPOT. Spot Forming Units below the detection limit are included as a value of '1'.
Percentage of Participants With Response by ELISPOT
Response rates regarding IFNγ producing T-cells measured by vaccinia-specific ELISPOT. A response to the vaccine was defined as either the appearance of a positive signal for participants without a positive signal at Baseline or an increase by a factor of at least 1.7 of the SFU/1 x 10E6 PBMC compared to the Baseline SFU/1 x 10E6 PBMC for participants with a positive signal at Baseline.
Percentage of Responders by ELISPOT
Responder rate measured by vaccinia specific ELISPOT. A participant was defined as a responder to the vaccine determined by ELISPOT if the participant had at least 1 post-baseline visit determined to be a response. A response to the vaccine was defined as either the appearance of a positive signal for participants without a positive signal at Baseline or an increase by a factor of at least 1.7 of the SFU/1 x 10E6 PBMC compared to the Baseline SFU/1 x 10E6 PBMC for participants with a positive signal at Baseline.
Correlation ELISA vs PRNT Titers
Pearson Correlation Coefficient between the ELISA titers and the PRNT titers at weeks 4, 6 and 8 based on the log10 transformed titer values
