Panel 8: Vaccines and immunology

Review and highlight of the significant advances made towards vaccine development and understanding of the immunology of otitis media

Birth outcomes in Aboriginal mother–infant pairs from the Northern Territory, Australia, who received 23-valent polysaccharide pneumococcal vaccination during pregnancy

We found a numerically higher rate of preterm births among women who received 23vPPV in pregnancy compared to unvaccinated pregnant women

A Rationale for Change: An Increase in Invasive Pneumococcal Disease in Fully Vaccinated Children

A review of cases informed a change from a "3 + 0" infant schedule to a "2 + 1" schedule

Genetic Manipulation of Group A Streptococcus-Gene Deletion by Allelic Replacement

An optimized, rapid method for creating markerless isogenic mutations that combines Gibson assembly cloning with a new temperature-sensitive plasmid, pLZts

Meningococcal B vaccine and meningococcal carriage in adolescents in Australia

Among Australian adolescents, the 4CMenB vaccine had no discernible effect on the carriage of disease-causing meningococci, including group B

Invasive group A Streptococcus disease in Australian children: 2016 to 2018 - a descriptive cohort study

Our aims were to describe the epidemiological distribution of paediatric invasive group A Streptococcus disease in Australia and correlate this with influenza notifications

Spatial patterns of tuberculosis and HIV coinfection in Ethiopia

Our study provides evidence for geographic clustering of tuberculosis/human immunodeficiency virus co-infection in Ethiopia

Impact of multidrug-resistant tuberculosis and its medications on adverse maternal and perinatal outcomes: Protocol for a systematic review and meta-Analysis

We aim to determine whether multidrug-resistant tuberculosis and its medications during pregnancy impact maternal and perinatal outcomes

What goes up must come down: dynamics of type 1 interferon signaling across the lifespan

Type 1 interferons (T1IFNs) are typically expressed in low concentrations under homeostatic conditions, but upon pathogenic insult or perturbation of the pathway, these critical immune signaling molecules can become either protectors from or drivers of pathology. While essential for initiating antiviral defense and modulating inflammation, dysregulation of T1IFN signaling can contribute to immunopathology, making it and its associated pathways prime targets for immune evasion and disruption by pathogens. 

Population pharmacokinetics of penicillin G: insights into increased clearance at low concentrations to guide development of improved long-acting formulations for syphilis

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.
