Stepwise perinatal immunization education improved infant vaccination rates for key vaccines and enhanced mothers' knowledge. This approach ensures better infant immunization status and maternal understanding of vaccination schedules.
Area of Science:
- Public Health
- Pediatrics
- Health Education
Background:
- Perinatal immunization education is crucial for infant vaccination outcomes.
- Current educational materials lack detailed evaluation across perinatal stages.
- A hypothesis proposed stepwise education would improve infant immunization and maternal knowledge.
Purpose of the Study:
- To evaluate the impact of stepwise perinatal immunization education on infant immunization status.
- To assess the effect of this education on maternal immunization knowledge.
Main Methods:
- A cluster-randomized controlled trial involving pregnant women across nine obstetric sites in Japan.
- Intervention group received stepwise education (prenatal, postnatal, 1-month postpartum).
- Control group received a general immunization information leaflet; outcomes assessed at 6 months.
Main Results:
- Higher completion rates for diphtheria, tetanus toxoid, and acellular pertussis/inactivated polio (DTaP-IPV) vaccine at 6 months in the intervention group.
- Shorter completion times for DTaP-IPV, Haemophilus influenzae type b (Hib), and 13-valent pneumococcal conjugate (PCV13) vaccines in the intervention group.
- Significantly greater improvement in maternal immunization knowledge scores in the intervention group.
Conclusions:
- Stepwise perinatal immunization education enhances adherence to vaccination schedules for essential infant vaccines.
- This educational strategy effectively improves maternal knowledge regarding immunizations.

The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
