Seropositivity was defined by a concentration of = 120 mIU/mL of anti-measles neutralizing antibody titer, as measured by the plaque reduction neutralization test (PRNT). | 56 days after MMR dose 1 vaccination (Day 56) | |
Secondary | Seroconversion Rate for Mumps 56 Days Post-vaccination | The seroconversion rate for mumps at 56 days post-vaccination was defined as the percentage of participants with a change in serostatus from negative to positive 56 days after vaccination. Seropositivity was defined as an optical density ratio = 1.10, measured using a commercial ELISA. Participants with equivocal serostatus at baseline are counted as non-responders. | 56 days after MMR dose 1 vaccination (Day 56) | |
Secondary | Seroconversion Rate for Rubella 56 Days Post-vaccination | The seroconversion rate for rubella at 56 days post-vaccination was defined as the percentage of participants with a change in serostatus from negative to positive 56 days after vaccination or a four-fold rise in concentration 56 days after vaccination if seropositive for rubella at baseline. Seropositivity is defined as a post-vaccination concentration of = 10 IU/mL measured using a commercial ELISA. | 56 days after MMR dose 1 vaccination (Day 56) | |
Secondary | Percentage of Participants With Japanese Encephalitis Seropositivity 28 Days Post-vaccination | Japanese encephalitis (JE) immunogenicity was assessed by the percentage of participants with demonstrated seropositivity 28 days after CD-JEV vaccination. Seropositivity was defined as an anti-JE serum neutralizing antibody titer of = 1:10, as measured by JE PRNT-50. | 28 days after CD-JEV vaccination (Day 28 for Group 1 and Day 84 for Group 2) | |
