Protection of newborns from infection can be achieved through maternal or vaccine-induced antibodies, but the factors influencing vaccine protection (correlate of protection) and subsequent infant immunity remain insufficiently understood. Further investigation is essential to optimize early-life vaccination strategies.
To determine whether the screening age for atrial fibrillation (AF) should be lowered for Indigenous Australians with the goal of reducing risk of stroke and other health burdens.
Vancomycin is used to treat serious gram-positive infections in children; however, effective dosing information for those aged 3 months to 18 years is limited. We aimed to determine an optimized dosing strategy for this age group.
The prevalence of impetigo and pharyngitis - which are both superficial group A streptococcus (GAS) infections that precede acute rheumatic fever - is poorly defined. Guidelines recommend the early diagnosis of both infections to prevent ARF; however, screening to enable the concurrent detection of these infections in high-risk populations has rarely been performed.
Convalscent plasma (CP) was identified as a potential therapy for COVID-19 available early in the pandemic.
A future Streptococcus pyogenes (Strep A) vaccine will ideally prevent a significant burden of lower limb cellulitis; however, natural immune responses to proposed vaccine antigens following an episode of cellulitis remain uncharacterized.
In 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.
Dried blood spot (DBS) antibiotic assays can facilitate pharmacokinetic (PK) investigations in situations where venous blood sampling is logistically and/or ethically challenging. The aim of this study was to establish, validate and demonstrate the application of a DBS amoxicillin assay for PK studies in vulnerable populations.
Group A streptococcus (GAS) infections, such as pharyngitis and impetigo, can lead to rheumatic fever and rheumatic heart disease (RHD). Australian Aboriginal and Torres Strait Islander populations experience high rates of RHD and GAS skin infection, yet rates of GAS pharyngitis are unclear.
The use of adjunctive antibiotics directed against exotoxin production in Staphylococcus aureus bacteremia (SAB) is widespread, and is recommended in many guidelines, but there is limited evidence underpinning this.
