The Australian Strep A Vaccine Initiative (ASAVI) is an Australian-led global initiative with the goal of reducing the disease burden caused by Group A Streptococcus (Strep A) infection through effective vaccination.

PICOBOO is a randomised, adaptive trial evaluating the immunogenicity and reactogenicity of licensed COVID-19 booster vaccines in immunocompetent individuals >12 years old. Here, we present data for seven different vaccines among three pre-specified participant strata defined by age and primary vaccine schedule.
This paper presents a comprehensive cardiac safety framework for early clinical development of Streptococcus pyogenes (Group A Streptococcus) vaccines, endorsed by the Strep A Vaccine Global Consortium and the Australian Strep A Vaccine Initiative. Given historical concerns about vaccine-associated acute rheumatic fever, we have established standardized echocardiography protocols integrated with clinical assessment for monitoring cardiac safety in early-phase vaccine trials.
Streptococcus pyogenes (Group A Streptococcus, Strep A) is a Gram-positive bacterium and one of the most significant global bacterial pathogens, with disproportionate disease burden affecting low and middle-income countries. Despite substantial mortality and immune sequelae caused by Strep A, no licensed vaccines exist, and correlates of protection remain unestablished.
Cytokines of the TGF-β superfamily control essential cell fate decisions via receptor regulated SMAD (R-SMAD) transcription factors. Ligand-induced R-SMAD phosphorylation in the cytosol triggers their activation and nuclear accumulation. We determine how R-SMADs are inactivated by dephosphorylation in the cell nucleus to counteract signaling by TGF-β superfamily ligands.
Immune surveillance by cytotoxic T cells eliminates tumor cells and cells infected by intracellular pathogens. This process relies on the presentation of antigenic peptides by Major Histocompatibility Complex class I (MHC-I) at the cell surface. The loading of these peptides onto MHC-I depends on the peptide loading complex (PLC) at the endoplasmic reticulum (ER).
This study aims to describe the pattern and trends in acute rheumatic fever (ARF)/rheumatic heart disease (RHD)-related hospitalisations and costs for Australians aged <65 years.
Pharyngitis, more commonly known as sore throat, is caused by viral and/or bacterial infections. Group A Streptococcus (Strep A) is the most common bacterial cause of pharyngitis. Strep A pharyngitis is an acute, self-limiting disease but if undertreated can lead to suppurative complications, nonsuppurative poststreptococcal immune-mediated diseases, and toxigenic presentations.
Although benzylpenicillin (penicillin G) is listed by the World Health Organization as an Essential Medicine, dose optimization is a persistent challenge, especially for long-acting intramuscular formulations. Maintaining sustained antibiotic exposure at target concentrations is crucial for secondary chemoprophylaxis of rheumatic heart disease and treatment of syphilis.
