This cohort study evaluates whether influenza A(H1N1) vaccination in pregnancy is associated with early childhood morbidity in offspring.
Question Is pandemic influenza A(H1N1) vaccination in pregnancy associated with an increased risk for early childhood morbidity in offspring?
Findings In this cohort study, children exposed to maternal vaccination during pregnancy were not significantly more likely to be hospitalized in early childhood than unexposed children.
Meaning These results support the safety profile of influenza A(H1N1) vaccine used in pregnancy.
