Have you heard that pregnant women who get a flu shot may pass some of that protection to their unborn baby?
That could be a good thing since the flu shot doesn't work in infants younger than 6 months old, so the CDC tested the theory on about 40,000 infants hoping to find that mom's vaccine would build antibodies in the womb.
Now, the verdict is, it's not true after all. There appears to be no difference in the number of illnesses in babies, whether or not mom got a flu shot during pregnancy. Even so, the CDC recommends a flu shot for all pregnant women to avoid serious complications from the virus.
