Pertussis immunization during pregnancy: results of a cross-sectional study among Italian healthcare workers

Factors Associated With Influenza Vaccination During Pregnancy: A Real-World Evidence-Based Study

Pregnant women are at increased risk of influenza-related complications. However, the rate of influenza vaccination among pregnant women in Taiwan is low. By analyzing real-world data in this study, we investigated the factors associated with influenza vaccination during pregnancy in Taiwan. This study was a cross-sectional study. We collected real-world data from 2 databases in Taiwan: the Birth Certificate Database and the National Health Insurance Research Database. The study population was pregnant between October 2014 and December 2016 in Taiwan. The multivariate logistic regression was performed to identify factors associated with influenza vaccination, including maternal sociodemographics, trimester, comorbidities, and health-care utilization. The vaccination rate of among pregnant women was 8.2%. Factors significantly associated with a high likelihood of influenza vaccination were age between 30 and 34 years (odds ratio [OR]: 1.14; 95% confidence interval [CI]: 1.10-1.19), second trimester (OR: 1.80; 95% CI: 1.75-1.85), income equal to or exceeding NT$ 38 201 (OR: 1.92; 95% CI: 1.86-1.99), hypertension (OR: 1.16; 95% CI: 1.05-1.29), cardiovascular disease (OR: 1.29; 95% CI: 1.17-1.42), autoimmune disease (OR: 1.47; 95% CI: 1.38-1.58), and chronic pulmonary disease (OR: 1.24; 95% CI: 1.18-1.31). A low level of urbanization, at least 1 hospitalization in the previous year, and the presence of pregnancy complications (eg, gestational diabetes, preeclampsia, and placenta previa) were associated with a lower likelihood rate of influenza vaccination. The influenza vaccination rate among pregnant women in Taiwan was low. Age, gestational age, income level, urbanization level, hypertension, cardiovascular disease, autoimmune disease, chronic pulmonary disease, and pregnancy complications may be associated with influenza vaccination among pregnant women.

Respiratory Syncytial Virus: Willingness towards a Future Vaccine among Pregnant Women in Italy

BACKGROUND

This cross-sectional survey was designed to evaluate pregnant women's awareness regarding Respiratory Syncytial Virus (RSV) infection and willingness to receive the vaccine during pregnancy and to vaccinate their newborn against RSV.

METHODS

An anonymous survey was administered from 20 April to 30 June 2023, to pregnant women aged ≥ 18 years attending gynecology wards of randomly selected public hospitals in southern Italy. A minimum sample size of 427 participants was calculated. The survey assessed women's socio-demographic characteristics, health-related information, their source(s) of information, and attitudes regarding RSV.

RESULTS

A total of 490 women participated. Those who were married/cohabiting, with a high-school degree compared to those who had a university degree, and those who needed additional information were more concerned that the newborn could acquire the RSV infection. The perceived utility of a future RSV vaccine administered during pregnancy was higher among those who were married/cohabiting, with a university degree, those with very good perceived health status, those who received information from healthcare workers, and those who needed additional information. Only 45.9% were willing to be vaccinated during pregnancy, and this was more likely among those with a university degree, with a very good perceived health status, who had received information from healthcare workers, and who needed more information. Finally, almost two-thirds (61.1%) were willing to vaccinate their newborn, and this was more likely among women with a university degree, with a very good perceived health status, and who needed additional information.

CONCLUSIONS

An education campaign regarding RSV infection and its vaccine is needed in order to improve women's perception and to support healthcare workers in promoting it when it will be available.
