[Analysis of the willingness and related factors of pregnant women in Shanghai City to receive influenza vaccines during pregnancy].

Objective: To analyze the willingness and related factors of pregnant women in Shanghai City to receive influenza vaccines during pregnancy. Methods: An online questionnaire survey was conducted among pregnant women who registered in maternal and child health hospitals in 16 districts of Shanghai. The basic information, health status during pregnancy, attitude towards influenza vaccination, and knowledge of influenza and influenza vaccine were collected, and χ² test and multivariate logistic regression analysis were used to analyze the willingness and related factors of pregnant women to receive influenza vaccines during pregnancy. Results: A total of 3 219 valid questionnaires were received, with 10.90% of pregnant women willing to receive influenza vaccination during pregnancy, 57.50% unwilling to receive vaccination and 31.59% holding an uncertain attitude. Among the pregnant women who were willing to receive the vaccine, 82.91% would take the initiative to know the relevant information about the influenza vaccine, and 87.18% understood the transmission routes of the flu. 32.09% believed that pregnant women could receive the influenza vaccination at any stage of pregnancy. Among those who were unwilling and held an uncertain attitude, the proportions of the above three questions were 47.06%, 83.95% and 17.80%, respectively. Among pregnant women who were unwilling to receive vaccination and held an uncertain attitude, the main reason for their vaccine hesitation was the concern about the safety of the vaccine for pregnant women and fetuses during pregnancy. Multivariate logistic regression analysis showed that pregnant women with higher education (OR=3.278, 95%CI: 1.678-6.406, P=0.001), second trimester (OR=1.542, 95%CI: 1.159-2.054, P=0.003), third pregnancy (OR=2.318, 95%CI: 1.008-5.331, P=0.048), and previous influenza vaccination (OR=1.552, 95%CI: 1.119-2.152, P=0.008) had a higher willingness to receive influenza vaccines during pregnancy. Conclusion: Pregnant women in Shanghai have a relatively low willingness to receive influenza vaccines during pregnancy, mainly due to concerns about vaccine safety.
