Background: Pregnant women are at a high-risk of influenza infection. We have previously reported a low influenza vaccination coverage rate (4.0%) in Korea during the 2006-2007 influenza season. We conducted follow-up studies in 2011-2012 and 2018-2019 to observe changes in influenza vaccination coverage.
Methods: Women who delivered at Inha University Hospital (Incheon, Korea) in 2011-2012 and 2018-2019 were enrolled in the study. We surveyed the rate of influenza vaccination, perception scores, and related factors through telephonic interviews and compared the results from 2011-2012 and 2018-2019 with those from 2006-2007.
Results: The number of survey respondents was 227 in 2006-2007, 152 in 2011-2012, and 171 in 2018-2019. The rate of vaccination coverage increased from 4.0% in 2006-2007 to 42.0% in 2011-2012 and 59.3% in 2018-2019. Perception scores also increased progressively from 3.8 in 2006-2007 to 4.2 in 2011-2012 and 5.1 in 2018-2019. Physician recommendations for influenza vaccination also increased from 4.8% in 2006-2007 to 36.8% in 2011-2012 and 49.7% in 2018-2019. The most common reason for not getting vaccinated was the lack of awareness of influenza vaccination during pregnancy (36.9%). The perception scores and physician recommendation rates were significantly lower for unvaccinated women (3.87 and 8.4%, respectively) than for vaccinated women (5.14 and 69.1%, respectively).
Conclusion: The influenza vaccination coverage rate in pregnant women has increased significantly since our study in 2006-2007. However, further improvement in the coverage rate is needed. There is a need for active and comprehensive publicity and education regarding this issue among physicians and pregnant women.

Influenza virus infections are a serious danger to people's health worldwide as they are responsible for seasonal flu outbreaks. There is an urgent need to improve the effectiveness and durability longevity of the immune response to influenza vaccines. We synthesized the CpG HP021 and examined the impact of it on the immune response to an influenza vaccine.

Objectives: Most studies on long-term sequelae of SARS-CoV-2-infection in children were conducted pre-Omicron and pre-dated vaccination rollout. We examined long-term risk of new-incident multi-systemic sequelae after SARS-CoV-2 Delta/Omicron infection in a multi-ethnic Asian pediatric population.
Methods: Retrospective cohort study of Singaporean children aged 1- 17 years infected during Delta/Omicron BA.

Introduction: The objective of our study was to estimate the influenza vaccine effectiveness for 2023/24 epidemic of co-circulating influenza A(H3N2) and B(Victoria) viruses in Beijing, China.
Methods: The surveillance-based study included all swabbed patients through influenza virological surveillance in Beijing, between October 2023 and March 2024. A Test-Negative Design(TND) was used to estimate influenza vaccine effectiveness(VE) against medically- attended laboratory-confirmed influenza in outpatient settings, also calculated the influenza vaccination rate(IVR).

The immune memory imprinted during an individual's initial influenza exposure (influenza imprinting) has long-lasting effects on the host's response to subsequent influenza infections and vaccinations. Here, we investigate how different influenza virus imprinting impacts the immune responses to subunit, inactivated virus, and protein-based nanoparticle vaccines in Balb/c mice. Our results indicated a phylogenetic distance-dependent effect of influenza imprinting on subunit hemagglutinin (HA) or formalin-inactivated (FI) virus vaccine immunizations.
