Seasonal Influenza (Flu) for Ob-Gyns
Seasonal Influenza 2014-2015
Neither CDC nor ACOG recommend one type of flu vaccine. All influenza vaccines available are recommended for use in pregnant women, with the exception of the live intranasal vaccine.
There have been no reports of any adverse outcomes in pregnant women or their infants. Thimerosal, a mercury-containing preservative used in multidose vials, has not been shown to cause any adverse effects except for occasional local skin reactions. There is no scientific evidence that thimerosal-containing vaccines cause adverse effects in children born to women who received vaccines with thimerosal. Hence, ACIP does not indicate a preference for thimerosal-containing or thimerosal-free vaccines for any group, including pregnant women (Committee Opinion #468).
All flu vaccines are either pregnancy category B or C. These are categories assigned by the FDA. Pregnancy Category B means that tests in animals have failed to demonstrate adverse effects on the fetus, however sufficient testing in pregnant women has not been conducted. Pregnancy Category C means that animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women.
However, despite these categories influenza vaccines are still recommended by CDC because millions of doses have been given to pregnant women with no adverse events occurring.

It is very important for individuals at high risk of developing flu related complications receive the flu vaccine. Individuals in this group include:
