âAny time you get a flu shot is better than not getting a flu shot, but my best guess is that getting your flu shot in mid-October will give you the best chance of avoiding the flu this year,â says Jorge P. Parada, MD, a professor of medicine and director of the infection control program at Loyola University in Chicago.
The best time to get vaccinated is early in the flu season, regardless of the stage of pregnancy, the guidelines state. However, pregnant women can get a flu shot at any time during flu season, which typically lasts from October to May.All women who are or become pregnant during the flu season should get the inactivated flu vaccine, which is also safe for women who have just given birth and those who are breast-feeding.lu shots not only protect pregnant women, but their infants as well. Babies can't be given flu vaccine until they are 6 months old, but receive flu antibodies from their vaccinated mother while in the womb.
