Is your girl in infant care/childcare? If not, perhaps not that crucial. That's my pediatrician's advice. My twins were in infant care since young and when they turned 1 yr, my pediatrician suggested I jab them to minimise the risk of them getting sick. Since then, every yr they will have a jab(as they are still in childcare). Incident of them falling sick is reduced but still have of course.The flu jab is not a 100% thingy. Just my opinion.
