Geometric Mean Titer of Anti-Chikungunya Antibodies as Measured by 50% Plaque Reduction Neutralization Test 28 Days After Last MV-CHIK Vaccination Primary · 28 days after last vaccination (Up to Day 56)

Participant serum was collected for determination of antibody responses by 50% plaque reduction neutralization test (PRNT50). Geometric Mean Titer (GMT) of functional antibodies as measured by PRNT50 were assessed. Geometric mean titers and GMT ratios were estimated by applying an analysis of variance (ANOVA) including the factor treatment group. This was done using log10 transformed data and taking the anti-log of the resulting point estimates for the least squares means, least squares means differences and the corresponding 2 sided 95% confidence intervals (CI). P-values were also provided t

Percentage of Participants With Solicited and Unsolicited Adverse Events Secondary · Up to Day 56

An adverse event (AE) includes any untoward medical occurrence in a participant to whom an IMP has been administered, not necessarily caused by or related to that product. An AE can therefore be any unfavourable or unintended sign, abnormal laboratory finding, symptom or disease temporally associated with the use of an IMP whether or not considered related to the IMP. The percentage of participants with solicited and unsolicited AEs was assessed.

Percentage of Participants With at Least 1 Serious Adverse Event Secondary · Up to Day 56

A serious adverse event (SAE) is any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, and consists of a congenital anomaly, birth defect or other important medical events. As per the protocol, adverse events were analyzed per treatment group but were not assessed with respect to individual vaccinations.

Cellular immunogenicity was determined by the evaluation of T cell immune response. Blood was collected for the isolation of peripheral blood mononuclear cells (PBMCs). PBMCs were isolated from whole blood to determine functional Interleukin 2 (IL-2)-producing T cells on day 0, 14, 28, 42, and 56 and in a subset of participants.
