A study published by the American Journal of Obstetrics & Gynecolog found that infants born to mothers who received the flu vaccine during pregnancy were between 45 to 48% less likely to be admitted to hospital with laboratory-confirmed influenza.
US researchers analysed data collected by a “vaccine surveillance network” over the course of seven influenza seasons from between 2002 and 2009. The data included information regarding over 1,500 babies who had been hospitalised with flu symptoms including fever, respiratory symptoms.
This study marks the first population-based, laboratory-confirmed study to demonstrate this benefit of the influenza vaccine during pregnancy.
In the UK, the NSH currently classes pregnant women in the “at risk” group and therefore suggest that they are vaccinated. For more information about the Flu jab and the current at risk group see our UK flu vaccination page.
