‘I'm glad my baby has weaned so I don't need to make that decision.’ Understanding breastfeeding-related COVID-19 vaccine narratives on social mediaDuring the coronavirus disease 2019 (COVID-19) pandemic, the infodemic has been highly visible. Vaccine-related advice and evidence-based guidelines for breastfeeding women have lagged, and, at times have been contradictory and confusing. Breastfeeding is an important public health issue with long-lasting health benefits for infants and mothers.

Quantifying the impact of contact tracing interview prioritisation strategies on disease transmission: A modelling studyContact tracing is an important public health measure used to reduce transmission of infectious diseases. Contact tracers typically conduct telephone interviews with cases to identify contacts and direct them to quarantine, with the aim of preventing onward transmission. However, in situations where caseloads exceed the capacity of the public health system, timely interviews may not be feasible for all cases. Here we present a modelling framework for assessing the impact of different case interview prioritisation strategies on disease transmission.

Serological Responses to Target Streptococcus pyogenes Vaccine Antigens in Patients With Proven Invasive β-Hemolytic Streptococcal InfectionsRising incidence of invasive β-hemolytic streptococcal (iBHS) infections has prompted consideration of vaccination as a preventative strategy for at-risk populations. The benefits of a vaccine targeting Lancefield group A (Streptococcus pyogenes; Strep A) would increase if cross-species immunity against Lancefield groups C/G (Streptococcus dysgalactiae subspecies equisimilis; SDSE) and B (Streptococcus agalactiae; GBS) was demonstrated.

Invasive group B streptococcal infections in Western Australia, 2000–2018Neonatal and puerperal sepsis are major manifestations of invasive group B streptococcal (Streptococcus agalactiae; iGBS) infections. International data indicate the importance of iGBS infections among non-pregnant adults.

Predictors of poor treatment outcomes among drug-resistant tuberculosis patients in Hunan province, ChinaDrug-resistant tuberculosis (DR-TB) is a significant public health concern, often resulting in poor treatment outcomes. This study aims to identify predictors of poor treatment outcomes among patients with DR-TB in Hunan Province, China.

Biases in Routine Influenza Surveillance Indicators Used to Monitor Infection Incidence and Recommendations for ImprovementMonitoring how the incidence of influenza infections changes over time is important for quantifying the transmission dynamics and clinical severity of influenza. Infection incidence is difficult to measure directly, and hence, other quantities which are more amenable to surveillance are used to monitor trends in infection levels, with the implicit assumption that they correlate with infection incidence.

The Platform Trial In COVID-19 priming and BOOsting : The immunogenicity, reactogenicity, and safety of licensed COVID-19 vaccinations administered as a second booster in BNT162b2PICOBOO is a randomised, adaptive trial evaluating the immunogenicity, reactogenicity, and safety of COVID-19 booster strategies. Here, we present data for second boosters among individuals aged 18-<50 and 50-<70 years old primed with BNT162b2 until Day (D) 84.

Improving the detection of congenital syphilis: reviewing test utility and adherence to recommendationsWestern Australia (WA) has experienced a resurgence of congenital syphilis. Appropriate microbiology testing of the neonate is recommended to confirm infection, including syphilis immunoglobulin M (IgM), rapid plasma reagin (RPR) paired with a maternal sample, and polymerase chain reaction (PCR) on placenta and nasal swabs.

Biomarkers of vaccine safety and efficacy in vulnerable populations: Lessons from the fourth international precision vaccines conferenceVaccination has been a cornerstone of public health, substantially reducing the global burden of infectious diseases, notably evident during the COVID-19 pandemic caused by SARS-CoV-2.

The Platform trial In COVID-19 vaccine priming and BOOsting (PICOBOO) booster vaccination substudy protocolCoronavirus-2019 (COVID-19) vaccination in Australia commenced in February 2021. The first vaccines recommended for use were AZD1222 and BNT162b2, both delivered as a two-dose primary schedule. In the absence of sustained immunity following immunisation, recommendations for booster vaccination have followed. It is likely that periodic boosting will be necessary for at least some Australians, but it is unknown what the optimal booster vaccines and schedules are or for whom vaccination should be recommended.
