Many infants discharged from the neonatal intensive care unit (NICU) are not up-to-date on immunizations. This study identified factors associated with underimmunization, highlighting the need for improved vaccination strategies before NICU discharge.
Area of Science:
- Neonatal care
- Pediatric immunology
- Public health
Background:
- Neonatal intensive care units (NICUs) provide critical care for vulnerable infants.
- Timely immunizations are crucial for protecting infants from vaccine-preventable diseases.
- Underimmunization in this population can lead to increased risk of infection.
Purpose of the Study:
- To determine immunization rates at discharge for infants aged 2 months and older from the NICU.
- To identify risk factors associated with underimmunization at NICU discharge.
Main Methods:
- Retrospective cohort study of 668 infants discharged from six Northern California Kaiser Permanente NICUs on or after 60 days of age.
- Immunization status at discharge was assessed.
- Logistic regression analysis was employed to identify risk factors for underimmunization.
Main Results:
- Only 51% of infants were up-to-date on routine immunizations at discharge.
- Twenty-seven percent of infants had received no vaccines.
- Mechanical ventilation, congenital heart disease, apnea, and bronchopulmonary dysplasia were associated with higher immunization rates, while surgery was linked to lower rates.
Conclusions:
- A substantial proportion of infants discharged from the NICU at 2 months or older were underimmunized.
- Interventions to improve immunization rates prior to NICU discharge are necessary.
- Targeted strategies may be required for infants with specific medical conditions or interventions.

Development of Immunocompetence
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.
