Adverse event reports of anaphylaxis after Comirnaty and Vaxzevria COVID-19 vaccinations, Western Australia, 22 February to 30 June 2021Within the first 4 months of the Western Australian COVID-19 immunisation programme, 49 suspected anaphylaxis cases were reported to the vaccine safety surveillance system. Twelve reports met Brighton Collaboration case definition, corresponding to rates of 15.9 and 17.7 per million doses of Vaxzevria and Comirnaty administered respectively.

Early treatment with fluvoxamine, bromhexine, cyproheptadine, and niclosamide to prevent clinical deterioration in patients with symptomatic COVID-19: a randomized clinical trialRepurposed drugs with host-directed antiviral and immunomodulatory properties have shown promise in the treatment of COVID-19, but few trials have studied combinations of these agents. The aim of this trial was to assess the effectiveness of affordable, widely available, repurposed drugs used in combination for treatment of COVID-19, which may be particularly relevant to low-resource countries.

Superior immunogenicity of mRNA over adenoviral vectored COVID-19 vaccines reflects B cell dynamics independent of anti-vector immunity: Implications for future pandemic vaccinesBoth vector and mRNA vaccines were an important part of the response to the COVID-19 pandemic and may be required in future outbreaks and pandemics. The aim of this study was to validate whether immunogenicity differs for adenoviral vectored (AdV) versus mRNA vaccines against SARS-CoV-2, and to investigate how anti-vector immunity and B cell dynamics modulate immunogenicity.

The inhibitory and inactivating effects of visible light on SARS-CoV-2: A narrative updatePrior to the coronavirus disease-19 pandemic, the germicidal effects of visible light were well known. This review provides an overview of new findings that suggest there are direct inactivating effects of visible light - particularly blue wavelengths on exposed severe acute respiratory syndrome coronavirus 2 virions, and inhibitory effects on viral replication in infected cells. These findings complement emerging evidence that there may be clinical benefits of orally administered blue light for limiting the severity of COVID-19.

Respiratory syncytial virus in children: epidemiology and clinical impact post-COVID-19Respiratory syncytial virus (RSV) remains a leading cause of mortality and morbidity worldwide. RSV seasonality was disrupted by COVID-19-associated nonpharmaceutical interventions (NPIs). We review RSV seasonality, molecular epidemiology, clinical manifestations, and community awareness to inform future prevention strategies.

Characterising the SARS-CoV-2 nucleocapsid (N) protein antibody responseSARS-CoV-2 nucleocapsid (N) protein antibodies can be used to identify the serological response to natural infection in those who have previously received a COVID-19 spike-based vaccine. Anti-N antibody responses can also be induced by inactivated whole SARS-CoV-2 virus vaccines, such as CoronaVac. We aimed to characterise antibody responses to the N protein following COVID-19 and following vaccination with CoronaVac.

COVID-19 in children: I. Epidemiology, prevention and indirect impactsChildren globally have been profoundly impacted by the coronavirus disease 2019 (COVID-19) pandemic. This review explores the direct and indirect public health impacts of COVID-19 on children. We discuss in detail the transmission dynamics, vaccination strategies and, importantly, the ‘shadow pandemic’, encompassing underappreciated indirect impacts of the pandemic on children.

BCG vaccination to reduce the impact of COVID-19 in healthcare workers: Protocol for a randomised controlled trial (BRACE trial)BCG vaccination modulates immune responses to unrelated pathogens. This off-target effect could reduce the impact of emerging pathogens. As a readily available, inexpensive intervention that has a well-established safety profile, BCG is a good candidate for protecting healthcare workers (HCWs) and other vulnerable groups against COVID-19.

Off-target effects of bacillus Calmette-Guerin vaccination on immune responses to SARS-CoV-2: implications for protection against severe COVID-19Because of its beneficial off-target effects against non-mycobacterial infectious diseases, bacillus Calmette-Guérin vaccination might be an accessible early intervention to boost protection against novel pathogens. Multiple epidemiological studies and randomised controlled trials are investigating the protective effect of BCG against coronavirus disease 2019 (COVID-19).
