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.
