The objective of this paper is to determine the acceptance rate of and inci
dence of adverse reactions to the influenza vaccine in pregnant women, and
to determine the immunized patients' attitudes toward future vaccination. A
total of 448 eligible pregnant women were offered the influenza vaccine at
routine prenatal visits. Vaccinated women were interviewed at their subseq
uent visit regarding adverse effects and attitudes toward future vaccinatio
n. Of the 448 women studied, 319 (71.2%) accepted the vaccine. There was no
difference in acceptance rates between English- and Spanish-speaking women
. Mild adverse reactions were experienced by 5.3%. Women who reported adver
se reactions were less likely to agree to future vaccination as compared wi
th unaffected women (64.7 vs. 94.0% p < 0.001). The influenza vaccine is re
adily accepted by pregnant women, and is infrequently associated with mild
side effects. Women who experience side effects are less likely to accept t
he vaccine in the future.
