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.
In mid-2018, the Australian childhood 13-valent pneumococcal conjugate vaccine schedule changed from 3+0 to 2+1, moving the third dose to 12 months of age, to address increasing breakthrough cases of invasive pneumococcal disease (IPD), predominantly in children aged >12 months. This study assessed the impact of this change using national IPD surveillance data.
Knowledge gaps regarding human immunity to Streptococcus pyogenes have impeded vaccine development. To address these gaps and evaluate vaccine candidates, we established a human challenge model of S. pyogenes pharyngitis. Here, we analyse antibody responses in serum and saliva against 19 antigens to identify characteristics distinguishing 19 participants who developed pharyngitis and 6 who did not.
While bacille-calmette-guerin (BCG) vaccination is one of the recommended strategies for preventing tuberculosis, its coverage is low in several countries, including Ethiopia. This study investigated the spatial co-distribution and drivers of TB prevalence and low BCG coverage in Ethiopia.
A retrospective study will review episodes of anaphylaxis during bee venom immunotherapy in children, any modifications made to the dosing schedule, and the subsequent outcomes over a nine-year period in Western Australia.
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
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.
This study adapts the Multiple Streams Framework (MSF) to explore why COVID-19 vaccine mandates were applied at sectoral and subnational levels in Vietnam while the central government maintained that vaccination was voluntary. Document analysis reveals that these mandates arose from the effective coupling of the three streams—problem, policy, and politics—in a setting of authoritarian rule, where the streams function differently (and more uniformly) compared to democratic contexts.
The Australian and New Zealand Paediatric Infectious Diseases (ANZPID) Group of the Australasian Society for Infectious Diseases (ASID) calls for urgent consideration of the needs and voices of children in response to the COVID-19 pandemic, and in planning for future pandemics.
