|
Purpose: We investigated the change of antibody titer to measles, mumps and rubella according to age after vaccination.
Methods: The IgG antibody titers to measles, mumps and rubella were tested on the residual serum from patients aged 7-20 years old after routine laboratory testing in the hospital with informed consent from the parents.
Results: Antibody to measles was present in 275 cases out of 408 cases with a positive rate of 67.4%, the mean IgG titer was 2.77¡¾1.18 Index. Antibody to mumps was present in 112 cases out of 408 cases with a positive rate of 27.5%, the mean IgG titer was 2.08¡¾1.29 Index. Antibody to rubella was present in 367 cases out of 408 cases with a positive rate of 90.0%, the mean IgG titer was 60.46¡¾63.47 IU/mL.
Conclusion: It is important to maintain a high rate of vaccination coverage in order to prevent an outbreak of measles, mumps, or rubella. It is also important to stress the maintenance of vaccination records for further reference.
