Methods: From September to December 2023, a cross-sectional study was conducted in Xiangxi People’s Hospital and Xiangxi Maternal and Child Health Hospital by convenience sampling using a structured questionnaire. The questionnaire involved the demographic information of pregnant women, their knowledge of influenza and influenza vaccine, and the reasons for refusing influenza vaccination. Results: A total of 396 pregnant women in Xiangxi region participated in the survey, of which 358 (90%) were under 35 years old. Most of the pregnant women were ethnic minorities, including 138 (35%) Miao and 184 (46%) Tujia. 248 (62.6%) pregnant women did not know or believed that influenza would not cause serious complications to pregnant women, and only 6.6% (n = 26) of the participants believed that influenza vaccination during pregnancy was acceptable. 7.1% (n = 28) of the participants knew that pregnant women could get influenza vaccine. 5.5% (n = 22) of the participants said that medical staff had recommended influenza vaccination. If the vaccine was free, 48.5% (n = 192) of the participants were willing to be vaccinated during pregnancy. The most common reasons given by participants for refusing vaccination were “I am concerned about the safety of the influenza vaccine for the fetus” and “I am concerned about the safety of the influenza vaccine for myself” (65.8% and 59.2%, respectively). Willingness to receive influenza vaccination was positively correlated with pregnancy complications (OR = 4.478;95% CI: 2.233~8.978), adverse pregnancy history (OR = 2.379;95% CI: 1.223~4.628), and the perception that influenza vaccination was recommended to pregnant women (OR=1.598;95% CI:1.151~2.217). Conclusion: Pregnant women in Xiangxi have poor knowledge of influenza and influenza vaccines and are less willing to receive influenza vaccination. Factors influencing the willingness to receive the flu vaccine include adverse pregnancy and delivery history, complications during pregnancy, and knowledge of flu and flu vaccines. The most common reason for refusing the flu vaccine is that pregnant women are concerned about the safety of the flu vaccine for the fetus and mother.
