  • Background: Children in care of the child welfare system (‘children in care’) are a vulnerable population who access preventive health services less than children not in care. Objective: To assess immunization coverage of a cohort children who have been in care in Canada and compare it to children who have never been in care. Methods: Three population-based administrative datasets were linked to assess immunization coverage for children at age two (N=44 206) and seven (N=42 241) for diphtheria, tetanus, pertussis, polio, Haemophilus influenzae type b (DTaP-IPV-Hib), meningococcal, and measles, mumps, rubella (MMR) vaccines. A child was considered to be in care if they spent any time in care before the age of assessment. Logistic regression was used to compare immunization status. Results: Immunization coverage for children in care at age two ranged from 54.3% (DTaP-IPV-Hib) to 81.4% (MMR) compared to those not in care which ranged from 74.2% (DTaP-IPV-Hib) to 87.4% (MMR). Coverage for children in care at age seven was 53.1% (DTaP-IPV) and 65.3% (MMR) compared to those not in care 76.6% (DTaP-IPV) and 83.4% (MMR). For both ages, the odds of being under vaccinated were higher for children in care for all vaccines (e.g. DTaP-IPV-Hib odds ratio [OR]: 2.43; 95% confidence interval [CI]: 1.72-3.44). For children not in care that live in households with competing demands (e.g. highly mobile lifestyle), their coverage was lower (e.g. 63.1% for DTaP-IPV-Hib) than those not in care without such demands (e.g. 76.4% for DTaP-IPV-Hib) but higher than children in care. Among the three groups, children in care had the highest odds of being under vaccinated (e.g. DTaP-IPV-Hib, OR: 2.72; 95% CI: 1.93-3.86). Conclusion: Children in care have lower immunization coverage than children not in care. Policies and practices should be examined to ensure optimal access to vaccination for these children.
