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.
