Background: Measles and rubella vaccines have been separately inoculated in Japan after failure of introduction of MMR in 1990s. Accumulated proportion of the vaccine coverage by age and its associated factors, however, has not been fully reported for both vaccines. To see the vaccine coverage both for measles and rubella by 2-years after birth, and examine the possible related factors.

Materials and Methods: One thousand and fifty children, who underwent a 3-years-old health checkup from April to December in 2004, participated in the study. A structured questionnaire was used to collect age of immunization, and guardians' knowledge and attitude. Cumulative immunization coverage rate was calculated for measles, rubella, and both of them. Crude and adjusted odds ratios of vaccine coverage for both measles and rubella by 2-years-old with possible related factors were calculated.

Results: Cumulative vaccine coverage for both measles and rubella was 55% by 2-years-old. Eleven children (1.0%) infected by measles and three (0.3%) infected by rubella. Completion of the two vaccines by 2-years-old was associated with getting information from child-rearing magazines (OR=1.66, 95%CI: 1.20-2.28), intention to finish all the immunizations before four years old (1.93, 1.50-2.47), and child care at nursery school during daytime (0.46, 0.39-0.63). After adjusting settlement area and child care in daytime, completion of both vaccines were still related with getting information from child-rearing magazines, and with intention to finish all the immunizations before 2-years-old.

Conclusions: To achieve sufficient vaccine coverage, favorable attitude of guardians toward early vaccination should be promoted through various communication media.

Learning Objectives:

• I will acquire to discuss and to recognize how to promote and status of vaccine administration regarding Measles and Rubella vaccine coverage in any other countries.
