Awesome that the CDC is telling pregnant women to get the flu shot when this is what is included in the manufacturer's insert: Pregnancy Category C: Animal reproduction studies have not been conducted with Fluzone vaccine. It is also not known whether Fluzone vaccine can cause fetal harm when administered to a pregnant... woman or can affect reproduction capacity. Fluzone vaccine should be given to a pregnant woman only if clearly needed. http://www.fda.gov/downloads/BiologicsBloodVaccines/Vaccines/Approv...
