Primary

MeasureTime frame
1) Non-inferiority for seropositivity rate for anti-measles, anti-mumps and antirubella IgG antibodies at 42 days after vaccination between the test group and the reference group 2) Non-inferiority for seroconversion rate for anti-measles, anti-mumps and antirubella IgG antibodies at 42 days after vaccination between the test group and the reference group 3)Lot-to-lot consistency of 3 batches of the test vaccine at 42 days after vaccination based on geometric mean titre ratio 4)Geometric mean titre of anti-measles, anti-mumps and anti-rubella IgG antibodies at 42 days after vaccination in the test group and the reference groupTimepoint: 1) Day 42 2) Day 42 3) Day 42 4) Day 42
