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).

Several viruses, including influenza A virus (IAV), encode viral factors to hijack cellular RNA biogenesis processes to direct the degradation of host mRNAs, termed "host shutoff." Host shutoff enables viruses to simultaneously reduce antiviral responses and provides preferential access for viral mRNAs to cellular translation machinery. IAV PA-X is one of these factors that selectively shuts off the global host genes.

Faculty of Nursing, University of Alberta, Edmonton, Alberta, Canada.
Background: Despite high COVID-19 vaccine coverage in Canada, vaccine acceptance and preferred delivery among newcomers, racialized persons, and those who primarily speak minority languages are not well understood. This national study explores COVID-19 vaccine acceptance, access to vaccines, and delivery preferences among ethnoculturally diverse population groups.
Methods: We conducted two national cross-sectional surveys during the pandemic (Dec 2020 and Oct-Nov 2021).

Influenza Division, National Center for Immunization and Respiratory Diseases, US Centers for Disease Control and Prevention, Atlanta, Georgia.
Importance: Increasing the understanding of vaccine effectiveness (VE) against levels of severe influenza in children could help increase uptake of influenza vaccination and strengthen vaccine policies globally.
Objective: To investigate VE in children by severity of influenza illness.
Design, Setting, And Participants: This case-control study with a test-negative design used data from 8 participating medical centers located in geographically different US states in the New Vaccine Surveillance Network from November 6, 2015, through April 8, 2020.
