Intraseason decline in influenza vaccine effectiveness during the 2016 southern hemisphere influenza season: A test-negative design study and phylogenetic assessment

Overall, the 2016 influenza vaccine showed good protection against laboratory-confirmed infection among general practice patients

Haemophilus influenzae remains the predominant otitis media pathogen in Australian children undergoing ventilation tube insertion in the PCV13 era

Understanding patterns of bacterial carriage and otitis media (OM) microbiology is crucial for assessing vaccine impact and informing policy. The microbiology of OM can vary with geography, time, and interventions like pneumococcal conjugate vaccines (PCVs). We evaluated the microbiology of nasopharyngeal and middle ear effusions in children living in Western Australia, 11 years following the introduction of PCV13.

Effectiveness of 2023 southern hemisphere influenza vaccines against severe influenza-associated illness: pooled estimates from eight countries using the test-negative design

Annual estimates of seasonal influenza vaccine effectiveness can guide global risk communication and vaccination strategies to mitigate influenza-associated illness. We aimed to evaluate vaccine effectiveness in countries using the 2023 southern hemisphere influenza vaccine formulation.

How immunity shapes the long-term dynamics of influenza H3N2

Since its emergence in 1968, influenza A H3N2 has caused yearly epidemics in temperate regions. While infection confers immunity against antigenically similar strains, new antigenically distinct strains that evade existing immunity regularly emerge ('antigenic drift'). Immunity at the individual level is complex, depending on an individual's lifetime infection history.

Effectiveness of trivalent flu vaccine in healthy young children

This paper reports some of the findings from the Western Australian Influenza Vaccine Effectiveness Study, commenced in 2008, to evaluate a program providing...

No role for neutrophil elastase in influenza-induced cellular recruitment, cytokine production or airway hyperresponsiveness in mice

Previous studies have suggested that in vitro modulation of neutrophil chemokines and inflammatory cytokines by neutrophil elastase (NE) does not translate to t

The impact of Influenza infection during early life on immune development

This study will investigate the why disease is worse in infants and how early life viral infection impacts the developing immune system.
