Healthcare Worker Patient Transmission, Influenza Vaccination, Pertussis Vaccine, Pregnant Women

Implementation of organizational adjustments can enhance involvement of healthcare teams in carrying out flu and pertussis vaccinations, and optimizing access to vaccines for women and their families. Pertussis vaccination of pregnant women is envisaged by the French Health Autority, considering that, given international experiences, vaccination during the second trimester of pregnancy is safe, effective, and would aim to protect babies during the first months of their life. Before considering such a recommendation in France, the acceptability of this strategy by pregnant women and health professionals must be considered.

Multicentre, descriptive study conducted in a declarative manner and supplemented by direct observation by an investigator. Main objectives: * Assess existing practices of the various actors involved in flu and pertussis vaccination of pregnant or postpartum women medically followed in maternity wards. * Assess acceptability of pertussis and flu vaccination during pregnancy by women medically followed in maternity wards, and by health professionals of theses facilities. Secondary objectives: * Assess flu and pertussis immunization coverage of pregnant and postpartum women and of health professionals working in maternity wards. * Assess the links between immunization coverage of health professionals and their current practices in promoting flu and pertussis vaccination of women in maternity wards. Main outcome measures: * Identify in each maternity hospital facilitators of flu and pertussis vaccination. * Proportion of women willing to be vaccinated against pertussis and flu during pregnancy. * Proportion of health professionals agreeing to vaccinate pregnant women against flu and pertussis. Secondary endpoints: * Flu and pertussis immunization coverage of pregnant and postpartum women. * Flu and pertussis immunization coverage of health professionals. * Proportion of patient records with vaccination trace. * Link between understanding of vaccines and vaccine-preventable diseases, and immunization coverage of health professionals. * Link between attitudes and practices of health professionals, and immunization coverage of patients. * Link between immunization coverage of patients and health professionals.
