Mehrabadi A, Dodds L, MacDonald NE, et al. - Researchers aimed at examining whether seasonal influenza vaccination in pregnancy is linked with adverse childhood health outcomes. They conducted a population-based retrospective cohort study using a birth registry linked with health administrative data. They used inverse probability of treatment weighting and included 28,255 live births in Nova Scotia, Canada, between October 1, 2010, and March 31, 2014, with a mean duration of follow-up of 3.6 years. Of these children, 10 227 (36.2%) were born to women who received seasonal influenza vaccination during pregnancy. Outcomes revealed no correlation of seasonal influenza vaccination in pregnancy with adverse early childhood health outcomes among offspring.
