RESUMEN
Influenza is caused by a highly infectious RNA virus, which usually occurs in a seasonal pattern with epidemics in the winter months. The objective of this study was to determine the uptake of the influenza vaccine in a pregnant population and ascertain the reasons why some women did not receive it. A prospective cohort study was conducted over a two-week period in January 2016 in the National Maternity Hospital Dublin, a tertiary referral maternity hospital delivering over 9000 infants per year. There were 504 women studied over the 2-week period. Overall, 197(39.1%) women received the vaccine at a mean gestational age 20.9 weeks (SD 7.0). Given the increased rates of influenza in the community and the associated implications for mother and infant, it is important that pregnant women are educated regarding the risks of influenza in pregnancy and encourage this cohort to be vaccinated.
