(HealthDay News) — There are no gender-specific differences in child mortality related to the type of vaccine last administered, according to a study presented at the annual meeting of the European Society for Paediatric Infectious Diseases, held from May 6–10 in Dublin.

Tessa Schurink-van 't Klooster, from the National Institute for Public Health and the Environment in Bilthoven, Netherlands, and colleagues analyzed mortality data in a cohort of all Dutch children (aged 0–11 years in 2000–2011), and comparisons were made by gender.

The researchers found that over 30,023,459 person years, 21,362 children died (mortality rate 7.1/10,000 person years). For girls, mortality rate ratios (MRRs) ranged between 0.81 (95% confidence interval, 0.74–0.89) in children 2–13 months old and 0.90 (95% confidence interval, 0.77–1.07) in children aged 9–11 years, compared to boys. Analysis by the type of vaccine last received did not significantly change MRRs.

"The findings of this large population-based study are reassuring for continued trust in the safety of the national immunization program in high income countries," Schurink-van 't Klooster said in a statement. "However, ongoing evaluation of potential non-specific effects of vaccination on mortality and morbidity is needed to provide accurate information of the benefits and risks of vaccination."
