Influenza vaccination among pregnant women in two hospitals in Sydney, NSW: what we can learn from women who decline vaccinationPregnant women are recognised as being at risk of serious illness from influenza. Despite this, and longstanding national recommendations for vaccination in pregnancy, vaccine uptake remains suboptimal. This study aims to determine factors associated with women declining influenza vaccination in pregnancy.

‘Corona is coming’: COVID-19 vaccination perspectives and experiences amongst Culturally and Linguistically Diverse West AustraliansCulturally and Linguistically Diverse (CALD) groups within high-income countries are at risk of being left behind by the COVID-19 vaccination rollout. They face both access and attitudinal barriers, including low trust in government and health authorities.

Effectiveness of 13-valent pneumococcal conjugate vaccine against hypoxic pneumonia and hospitalisation in Eastern Highlands Province, Papua New Guinea: An observational cohort studyPneumonia is a leading cause of childhood mortality with Streptococcus pneumoniae a major contributor. Pneumococcal conjugate vaccines (PCVs) have been introduced into immunisation programs in many low- to middle-income countries yet there is a paucity of data evaluating the effectiveness in these settings. We assess the effectiveness of 13-valent PCV against hypoxic pneumonia, hospitalisation and other clinical endpoints in children <5 years living in Eastern Highlands Province, Papua New Guinea).

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

Streptococcus pyogenes pharyngitis elicits diverse antibody responses to key vaccine antigens influenced by the imprint of past infectionsKnowledge gaps regarding human immunity to Streptococcus pyogenes have impeded vaccine development. To address these gaps and evaluate vaccine candidates, we established a human challenge model of S. pyogenes pharyngitis. Here, we analyse antibody responses in serum and saliva against 19 antigens to identify characteristics distinguishing 19 participants who developed pharyngitis and 6 who did not.

Clinician perceptions of research priorities for the management of noncritically ill patients admitted to hospital with SARS-CoV-2 infectionThe changing phenotype of coronarvirus disease 2019 (COVID-19) may quickly render guideline-recommended interventions obsolete. We developed a 40-question clinician survey in consultation with the Australasian COVID-19 Trial site investigators. The survey was designed to assess clinician perceptions of the current treatment strategies and future research priorities in the management of non-critically ill patients admitted to hospital with SARS-CoV-2 infection.
Research
Otitis-prone children produce functional antibodies to pneumolysin and pneumococcal polysaccharidesThe production of functional antipneumococcal antibodies in otitisprone children demonstrates that they respond to the current pneumococcal conjugate vaccine (PCV)and are likely to respond to pneumolysin-based vaccines as effectively as healthy children.

Vaccine hesitancy, refusal and access barriers: The need for clarity in terminologyWe propose more precision in the term 'vaccine hesitancy' is needed particularly since much under-vaccination arises from factors related to access
