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.

This retrospective observational study compared the costs of RSV and influenza hospitalizations in adults aged ≥18 years admitted to the Spanish National Healthcare System between 2016 and 2019. Mean costs per hospitalization episode were compared using a multivariable log-gamma generalized linear model adjusted by age, risk group and calendar year.
