Should providers wait until the second trimester of pregnancy to give the inactivated H1N1 vaccine to pregnant women?
Available data indicate that flu vaccine does not cause fetal harm or affect fertility when given to a pregnant woman. Pregnant women and newborns are at increased risk for flu complications, and all women who are pregnant or will be pregnant during flu season should be vaccinated with inactivated H1N1 vaccine. Vaccination can occur during any trimester of the pregnancy. Benefits of vaccinating pregnant women usually outweigh potential risks from the vaccine.
