  •   Objective  To assess the level of health literacy about influenza vaccination among pregnant and postpartum women in China, and to explore the factors influencing vaccine literacy.  Methods  From January 17, 2024 to March 14, 2024, a stratified proportional sampling method was used to conduct surveys among pregnant and postpartum women in nine province/autonomous region/municipalities representing the Eastern, Central, Western, and Northeastern regions of China. The study utilized the Chinese version of the health literacy about vaccination in adulthood in Italian (HLVa-IT), to assess maternal functional vaccine literacy and interactive-critical vaccine literacy. Each scale considered achieving 80% of the total score as the standard for having vaccine literacy.  Results  A total of 2 035 valid questionnaires were collected from January 17 to March 14, 2024. 13.6% of these women had interactive-critical vaccine literacy. The results of the multivariate logistic stepwise regression analysis revealed that pregnant women who were not healthcare workers had a lower rate of functional vaccine literacy for influenza vaccination (aOR=2.236, 95% CI: 1.628-3.071, P < 0.001). Conversely, pregnant women whose insurance covered the cost of influenza vaccination during pregnancy (aOR=0.665, 95% CI: 0.479-0.923, P=0.015), those who had family support for influenza vaccination during pregnancy (aOR=0.355, 95% CI: 0.251-0.502, P < 0.001), those who had received influenza vaccination outside of pregnancy (aOR=0.691, 95% CI: 0.524-0.911, P=0.009), and those who perceived a decline in health status during pregnancy (aOR=0.754, 95% CI: 0.576-0.988, P=0.041) had higher rates of functional vaccine literacy for influenza vaccination. Additionally, pregnant women who were not healthcare workers (aOR=1.929, 95% CI: 1.121-3.318, P=0.018) and those who had not been informed by their doctors about vaccination during pregnancy (aOR=1.821, 95% CI: 1.070-3.098, P=0.027) had lower rates of critical-interactive vaccine literacy for influenza vaccination. On the other hand, pregnant women whose insurance covered the cost of influenza vaccination during pregnancy (aOR=0.537, 95% CI: 0.313-0.923, P=0.024), those who had family support for influenza vaccination during pregnancy (aOR=0.193, 95% CI: 0.114-0.328, P < 0.001), and those who had received influenza vaccination outside of pregnancy (aOR=0.505, 95% CI: 0.306-0.832, P=0.007) had higher rates of critical-interactive vaccine literacy for influenza vaccination.  Conclusions  The overall level of influenza vaccination literacy among pregnant women in China is relatively low, and their ability to comprehend, analyze, and utilize information about influenza vaccines needs improvement.
