Self-reported prenatal influenza vaccination and early childhood vaccine series completion
Pages 8-12
Erika L. Fuchs
Abstract
Background
No studies have examined associations between prenatal vaccination and childhood vaccination. Mothers who refuse influenza vaccinations during pregnancy report similar attitudes and beliefs to those who refuse vaccinations for their children. The objective of this study was to examine the association between self-reported prenatal influenza vaccination and early childhood vaccination.
Methods
A retrospective cohort study was conducted with existing surveillance data from 4022 mothers who responded to the 2009–2011 Minnesota Pregnancy Risk Assessment Monitoring System survey and child vaccination records from the Minnesota Immunization Information Connection database. The childhood vaccine series outcome included the following vaccines: diphtheria, tetanus, and pertussis; poliovirus; measles, mumps, and rubella; Haemophilus influenzae type b (Hib); hepatitis B; varicella; and pneumococcal conjugate. To evaluate the association between self-reported prenatal influenza vaccination and early childhood vaccination, unadjusted and adjusted logistic regression was used to estimate log odds for childhood vaccination status, while margins post-estimation commands were used to obtain predicted probabilities and risk differences.
Results
Vaccine series completion was 10.86% higher (95% confidence interval (CI) 7.33%–14.40%, adjusted and weighted model) in children of mothers who had a prenatal influenza vaccine compared to those who did not. For individual vaccines in the recommended series, risk differences ranged from 7.83% (95% CI 5.37%, 10.30%) for the Hib vaccine to 10.06% (95% CI 7.29%, 12.83%) for the hepatitis B vaccine.
Conclusion
Self-reported prenatal influenza vaccination was associated with increased early childhood vaccination. More research is needed to confirm these results and identify potential intervention strategies.

A double-risk monitoring and movement restriction policy for Ebola entry screening at airports in the United States
Original Research Article

Abstract
This paper provides an alternative policy for Ebola entry screening at airports in the United States. This alternative policy considers a social contact tracing (SCT) risk level, in addition to the current health risk level used by the CDC. The performances of both policies are compared based on the scenarios that occur and the expected cost associated with implementing such policies. Sensitivity analysis is performed to identify conditions under which one policy dominates the other policy. This analysis takes into account that the alternative policy requires additional data collection, which is balanced by a more cost-effective allocation of resources.
