Abstract
Open AccessThe national influenza vaccination program for the 2023-2024 season targeted influenza immunization for children aged 6 months to 13 years, pregnant women, and seniors aged 65 years and older. This study aimed to analyze the primary outcomes of the national influenza vaccination program for the specified season. The vaccination rates for the identified groups were 82.5% for older adults and 53.0% for pregnant women, reflecting increases of 0.6 and 2.6 percentage points, respectively, compared with the corresponding values in the preceding season. Conversely, the vaccination rate for children declined by 1.5 percentage points, reaching 69.5%. There were 176 reported cases of adverse events following influenza vaccination, equaling 1.5 reports per 100,000 vaccinations. We intend to investigate the principal findings for the 2023-2024 season and use them as a foundation for improving the national influenza vaccination program in the future.
