It’s not too late for the flu vaccine for this year! The flu vaccine in pregnancy has been shown to benefit both the pregnant woman and the fetus in a few different ways.
Duke University did a study of 1600+ women showing those who received the flu vaccine were significantly less likely to require a hospital visit or hospital stay overnight during their pregnancy than those that did NOT get the vaccine.
Those that received the vaccine had babies born at a higher weight and longer gestation than those that did not receive the vaccine.
Researchers may say that there are confounding aspects to the study. Vaccinated women were in for prenatal care earlier than those that did not receive the vaccine. So, maybe the more conscientious women are more likely to take the vaccine. Interesting findings . . .
