Immunogenicity and Safety of a 2 + 1 DTPa Priming Schedule in Australian Infants and the Impact of Maternally Derived Antibodies on Pertussis Antibody Responses up to 4 Years of AgeWe assessed the impact of maternally derived pertussis antibodies on infant responses to a 2 + 1 vaccine schedule (6 weeks, 12 weeks, and 12 months). Infants with baseline antibodies showed lower IgG responses following the primary vaccination series, but this did not impair booster responses at 4 years of age.

Prevention of rheumatic heart disease in New Zealand: High-dose subcutaneous benzathine penicillin is cost-saving compared with traditional intramuscular injectionsAcute rheumatic fever is a preventable condition that can lead to chronic illness and early death. Standard prevention with 4-weekly intramuscular (IM) benzathine penicillin G (BPG) injections for ≥10 years may be associated with poor adherence. High-dose 10-weekly subcutaneous penicillin injections (SCIP) may improve adherence by reducing injection frequency.

Facilitating knowledge transfer during Australia’s COVID-19 vaccine rollout: an examination of ‘Functional Dialogues’ as an approach to bridge the evidence–policy gapOur interdisciplinary team initiated a project to inform the COVID-19 vaccination programme. We developed a novel research co-creation approach to share emerging findings with government.

World Society for Pediatric Infectious Diseases calls for action to ensure fair prices for vaccinesThe eradication of smallpox is considered one of the greatest achievements of humankind, thanks to vaccination. The widespread availability of childhood vaccines has substantially reduced childhood morbidity and mortality. Devastating infections, such as polio, have almost disappeared due to vaccination. In 2021, it was estimated that vaccination against ten selected pathogens will have averted 69 million deaths between 2000 and 2030. Increases in vaccine coverage and introduction of additional vaccines should reduce lifetime mortality by 72% in the 2019 birth cohort. However, access to vaccines that prevent life-threatening and disabling infectious diseases remains unequal.

Immunogenicity, reactogenicity, and IgE-mediated immune responses of a mixed whole-cell and acellular pertussis vaccine schedule in Australian infants: A randomised, double-blind, noninferiority trialIn many countries, infant vaccination with acellular pertussis (aP) vaccines has replaced use of more reactogenic whole-cell pertussis (wP) vaccines. Based on immunological and epidemiological evidence, we hypothesised that substituting the first aP dose in the routine vaccination schedule with wP vaccine might protect against IgE-mediated food allergy. We aimed to compare reactogenicity, immunogenicity, and IgE-mediated responses of a mixed wP/aP primary schedule versus the standard aP-only schedule.

Erratum: Attitudes, perceptions, and experiences of Western Australians towards vaccine safety surveillance systems following COVID-19 vaccines: A qualitative descriptive study (Australian and New Zealand Journal of Public Health (2024) 48(1), (S132602002Concerns regarding adverse events following immunisation are a barrier to vaccine uptake. Health professionals use vaccine safety surveillance systems (VSSS) to monitor vaccines and inform the public of safety data. With little known about public attitudes, perceptions, and experiences with VSSS, we examined them in the context of COVID-19 vaccinations in Western Australia.

COVID-19 vaccine Mandates: An Australian attitudinal studyThe rollout of vaccines against COVID-19 is prompting governments and the private sector to adopt mandates. However, there has been little conceptual analysis of the types of mandates available, nor empirical analysis of how the public thinks about different mandates and why. Our conceptual study examines available instruments, how they have been implemented pre-COVID, and their use for COVID-19 globally.

Levels of pneumococcal conjugate vaccine coverage and indirect protection against invasive pneumococcal disease and pneumonia hospitalisations in Australia: An observational studyThere is limited empiric evidence on the coverage of pneumococcal conjugate vaccines (PCVs) required to generate substantial indirect protection. We investigate the association between population PCV coverage and indirect protection against invasive pneumococcal disease (IPD) and pneumonia hospitalisations among undervaccinated Australian children.

Bacille Calmette-Guérin vaccine reprograms human neonatal lipid metabolism in vivo and in vitroVaccines have generally been developed with limited insight into their molecular impact. While systems vaccinology enables characterization of mechanisms of action, these tools have yet to be applied to infants, who are at high risk of infection and receive the most vaccines. Bacille Calmette-Guérin (BCG) protects infants against disseminated tuberculosis (TB) and TB-unrelated infections via incompletely understood mechanisms.

PCV10 elicits Protein D IgG responses in Papua New Guinean children but has no impact on NTHi carriage in the first two years of lifeNasopharyngeal colonisation with nontypeable Haemophilus influenzae (NTHi) is associated with development of infections including pneumonia and otitis media. The 10-valent pneumococcal conjugate vaccine (PCV10) uses NTHi Protein D (PD) as a carrier. Papua New Guinean children have exceptionally early and dense NTHi carriage, and high rates of NTHi-associated disease.
