An infant mouse model of influenza-driven nontypeable Haemophilus influenzae colonization and acute otitis media suitable for preclinical testing of novel therapiesNontypeable Haemophilus influenzae (NTHi) is a major otitis media (OM) pathogen, with colonization a prerequisite for disease development. Most acute OM is in children <5 years old, with recurrent and chronic OM impacting hearing and learning. Therapies to prevent NTHi colonization and/or disease are needed, especially for young children. Respiratory viruses are implicated in driving the development of bacterial OM in children.

A Prospective Study Investigating the Impact of Obesity on the Immune Response to the Quadrivalent Influenza Vaccine in Children and AdolescentsObesity can increase the severity of influenza infection. Data are limited regarding immune responses to influenza vaccination in obese children. We aimed to investigate the impact of obesity on quadrivalent influenza vaccine responses in children.

Evidence of maternal transfer of antigen-specific antibodies in serum and breast milk to infants at high-risk of S. pneumoniae and H. influenzae diseaseChildren in low-mid income countries, and First Nations children in high-income countries, experience disproportionately high rates of Streptococcus pneumoniae and Haemophilus influenzae infections and diseases including pneumonia and otitis media.

Altered Behavior in Encephalitis: Insights From the Australian Childhood Encephalitis Study, 2013-2018Altered mental status is a major criterion for a diagnosis of encephalitis to be made with alteration in behavior, a key manifestation of altered mental status. We reviewed all evaluated cases identified by the Australian Childhood Encephalitis study between May 2013 and June 2018.

Immune impacts of infant whole-cell and acellular pertussis vaccination on co-administered vaccinesWe compared the effect of a heterologous wP/aP/aP primary series (hereafter mixed wP/aP) versus a homologous aP/aP/aP primary schedule (hereafter aP-only) on antibody responses to co-administered vaccine antigens in infants and toddlers.

Persistence of the immune responses and cross-neutralizing activity with Variants of Concern following two doses of adjuvanted SCB-2019 COVID-19 vaccineWe have previously reported the safety and immunogenicity four weeks after two doses of the Clover COVID-19 vaccine candidate, SCB-2019, a stabilized pre-fusion form of the SARS-CoV-2 S-protein (S-trimer). We now report persistence of antibodies up to 6 months after vaccination, and cross-neutralization titers against three Variants of Concern.

Predictors of hospital readmission in infants less than 3 months oldTo examine rates and predictors of 7-day readmission in infants hospitalised before 3 months of age with infectious and non-infectious conditions. A retrospective population-based data-linkage study of 121 854 infants from a 5-year metropolitan birth cohort (2008-2012). Cox proportional hazard models were used to examine associations between infant and maternal factors with 7-day readmission.

Nasopharyngeal density of respiratory viruses in childhood pneumonia in a highly vaccinated setting: findings from a case-control studyDetection of pneumonia-causing respiratory viruses in the nasopharynx of asymptomatic children has made their actual contribution to pneumonia unclear. We compared nasopharyngeal viral density between children with and without pneumonia to understand if viral density could be used to diagnose pneumonia.

Immunogenicity and Immune Memory after a Pneumococcal Polysaccharide Vaccine Booster in a High-Risk Population Primed with Pneumococcal Conjugate VaccinePPV is immunogenic in 9-month-old children at high risk of pneumococcal infections and does not affect the capacity to produce protective immune responses
