Objective: Influenza, even though it can affect people of any age, is usually a self-limiting infection. However, it is an important and remarkable disease due to the reasons such as leading to epidemics and pandemics, disrupting work and school attendance, and causing serious morbidity and mortality, especially in risk groups. Influenza may cause social and economic losses as well as fatal complications especially in the risk groups such as pregnant women. On the basis of this observation, our study aimed at retrospectively reviewing the answers of the pregnant women, who have visited our clinic, to the questions we routinely asked them as a component of their history of immunization, about their flu vaccination status and, if they have not been vaccinated, about the reason of this choice. Method: The pregnant women in the 18-50 age range, who have visited the Hospital of Zonguldak Bülent Ecevit University Medical School between 1st September 2019 and 1st February 2020, regardless of any other criterion, were asked about their educational status and whether they have had a flu vaccine during pregnancy. Those who have not been vaccinated were asked about the reason for not receiving the vaccine; whether they did not know about the vaccine, whether they thought that they did not need it or that the vaccine might do harm to their babies. Thus, the information about the 267 pregnant women in total was recorded. Findings: A total of 267 pregnant women, of whom 216 (80,9%) were under 35 years of age, and 51 (19,1%) aged 35 and over were included in our study and the mean age of the pregnant women was found to be 29,03 ± 6,11. Of the pregnant women six (2,2%) have received the flu vaccine and 261 (97,8%) have not been vaccinated against flu. Of the 261 pregnant women, 164 (62,8%), 30 (11,5%) and 67 (25,7%) answered "I did not know", "I did not need" and "It might cause harm", respectively, as a reason for not having a flu vaccine. There was no statistically significant difference between the educational status and age groups in terms of being vaccinated (p = 1,000). Accordingly, it is noteworthy that pregnant women, regardless of their age and educational status, have not been informed sufficiently about the influenza vaccine. Conclusion: In spite of the proven effectiveness of the vaccine, the seasonal influenza vaccination rates are still low around the world and in our country. In fact, when the literature is examined, it is striking that there are similar situations in different regions of the world. The reasons why the influenza vaccination rate among pregnant women was found to be as low as 2,2% in our study have common aspects with those in similar studies. The majority of pregnant women have not been informed that they should receive the flu vaccine. In this regard, family physicians and physicians providing secondary healthcare have a great duty. In the light of this fact, pregnant women should definitely be informed at pregnancy schools and family health centers about the necessity for vaccination.
