Pregnant women who have the flu vaccine during the flu season could be less likely to give birth prematurely or to low birth weight babies.
A new study, published by PLoS Medicine, showed that mums-to-be who had the flu jab and gave birth during flu season were 40% less likely to have a premature birth than unvaccinated mums.
Researchers also found that mums who were given the vaccine during pregnancy were 69% less likely to give birth to a low birth weight baby.
“This was an observational study and can only show that there was an association between flu vaccination during pregnancy and reduced risk of premature birth and low birth weight,” said researcher Dr Saad Omer.
The study looked at 4,000 mums who gave birth during the flu season.
Additional research will be needed confirm the results and to show any causal link between the two.
