Following our study of attitudes, barriers, and intentions concerning the influenza vaccination among pregnant women in South Korea, we discovered that women displaying a more positive attitude toward the influenza vaccination were more likely to receive it during their pregnancy. We also found that attitudes toward vaccination were more positive among vaccinated pregnant women than among those who were unvaccinated. Furthermore, women showed a greater intention to get vaccinated if a clinician, rather than friends, recommended it. The major perceived barriers to receiving an influenza vaccination were being pregnant, fearing harm to the baby, feeling healthy, and thinking it is unnecessary.
