Compliance of Pregnant Women with Recommendations Regarding Pertussis, Flu and COVID-19 Vaccination During Pregnancy

Background: Many vaccines are safe and recommended during pregnancy. Transmission of maternal antibodies produced in large quantities after vaccination protects the neonate in the first months of life, until the first vaccinations in infancy. In Poland, at the time of the study, influenza, pertussis, and COVID-19 vaccines were recommended during pregnancy. Methods: The authors performed a survey study in a group of 591 post-partum women. They were asked about the safety of pertussis, influenza and COVID-19 vaccines in pregnancy. Data regarding vaccination during pregnancy according to Polish recommendations in relation to the type of vaccine were also analysed. Results: Although 50% of patients reported that, in their opinion, the pertussis vaccine is safe and recommended during pregnancy, only 17% were vaccinated. Similar results authors obtained regarding the influenza vaccine (51% and 6%, respectively). The highest knowledge and compliance with recommendations correlation to the education level was observed in women with college and university education: 65% of them thought that pertussis vaccine is safe and recommended during pregnancy; 27% of them were vaccinated; 63% of them reported that they know that influenza vaccine is recommended during pregnancy and 9% were vaccinated. In a group with the lowest education, 14% reported that the pertussis vaccine is recommended as well as 24%-influenza vaccine. No patient in this group was vaccinated during pregnancy. Conclusions: Low compliance of pregnant women was confirmed in our study, and the desperate necessity of patients’ education regarding the safety of recommended vaccines is warranted. We showed that even patients who know that the vaccine is recommended do not receive vaccination, and the lower the education level, the lower the compliance.
