Biological: Vaccination

high antibody titers

OTHER

Antibody titers higher than protection level

Other: No Vaccination

Interventions

VaccinationBIOLOGICAL

Patients with higher antibody titers will accept vaccination. There are two vaccines provided in this study: hepatitis B vaccine measles-rubella combined vaccine
