Accumulating evidence indicates that antibiotic exposure may lead to impaired vaccine responses, however the mechanisms underlying this association remain poorly understood. Here we prospectively followed 191 healthy, vaginally born, term infants from birth to 15 months, using a systems vaccinology approach to assess the effects of antibiotic exposure on immune responses to vaccination.
Understanding 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.

Dynamic molecular changes in early life follow a robust ontogeny as the infant immune system adapts to the demands of its new environment. Studies of plasma immunomodulatory cytokines and chemokines have previously demonstrated ontogenetic patterns of immune development across the first week of life. However, how plasma cytokine and chemokines concentrations evolve over the first 4 months of life remains unknown.
Chronic suppurative otitis media (CSOM), sometimes referred to as chronic otitis media (COM), is a chronic inflammation and often polymicrobial infection of the middle ear and mastoid cavity, characterised by ear discharge (otorrhoea) through a perforated tympanic membrane. The predominant symptoms of CSOM are ear discharge and hearing loss. Systemic antibiotics are commonly used to treat people with CSOM. This is the first update to the review published in 2021, and is one of a suite of seven Cochrane reviews evaluating the effects of non-surgical interventions for CSOM.

Although uncommon, invasive meningococcal disease (IMD) results in death in 5%-10% of cases in healthy children and adolescents. This study aimed to examine demographics, clinical presentation, treatment and outcomes of Australian children hospitalized with IMD during the introduction of the meningococcal vaccine program, overall and by serogroup/disease severity.
The first peanut oral immunotherapy (OIT) for children was approved by the US Food and Drug Administration (FDA) in 2020. While clinical efficacy is established, evidence on cost-effectiveness-whether the benefits outweigh the costs and adverse effects-remains limited. A variant of OIT, known as probiotic and peanut OIT (PPOIT), has shown similar efficacy in trials.
Pneumococcal conjugate vaccine (PCV) prevents pneumococcal disease and pneumonia, but indirect effects are poorly understood in low-coverage, high-burden settings like Papua New Guinea (PNG). PNG introduced 13-valent PCV (PCV13) in 2014. We aimed to assess direct and indirect effectiveness of PCV13 against vaccine-type pneumococcal carriage among children with pneumonia or suspected meningitis in PNG
