Nuvaxovid NVX-CoV2373 vaccine safety profile: real-world data evidence after 100,000 doses, Australia, 2022 to 2023.

IntroductionNuvaxovid became available in Australia from February 2022, a year after the first COVID-19 vaccines. This protein-based vaccine was an alternative for people who had had an adverse event to and/or were hesitant to receive an mRNA or adenovirus-based COVID-19 vaccine. Although safety from clinical trials was reassuring, small trial populations, low administration rates and limited post-licensure intelligence meant potential rare adverse events were underinformed.

Systematic Review of Avian Influenza Virus Infection and Outcomes during Pregnancy.

Human cases of avian influenza A(H5N2) and A(H5N1) viruses associated with outbreaks in birds and mammals are increasing globally, raising concerns about the possibility of a future avian influenza pandemic. We conducted a systematic review examining 30 reported cases of avian influenza in pregnant women. We found high mortality rates for mothers (90.

Clinical phenotype of COVID-19 vaccine-associated myocarditis in Victoria, 2021-22: a cross-sectional study.

Objectives: To describe myocarditis as an adverse event after coronavirus disease 2019 (COVID-19) vaccination, including a detailed description of clinical phenotypes and diagnostic test results and differences by age, sex, and degree of troponin level elevation.

Study Design: Retrospective cross-sectional study.

Setting, Participants: Cases of suspected myocarditis following the administration of a COVID-19 vaccine in Victoria during 22 February 2021 - 30 September 2022 reported to Surveillance of Adverse Events Following Vaccination In the Community (SAEFVIC), with symptom onset within 14 days of vaccination, and deemed to be confirmed myocarditis according to the Brighton Collaboration Criteria.

Protocol for an embedded randomised controlled trial of Early versus Late Stopping of Antibiotics in children with Febrile Neutropenia (ELSA-FN).

In children with cancer, febrile neutropenia (FN) is one of the most common complications of treatment, a leading cause of unplanned and prolonged hospital admission and is the key driver of antibiotic exposure. Co-designed with key stakeholders, 'Early versus Late Stopping of Antibiotics in high-risk FN' (ELSA-FN) is a randomised controlled, non-inferiority trial that compares stopping antibiotics in clinically stable patients after 48 hours with the current standard of care, continuing antibiotics until absolute neutrophil recovery. As an Australian first, we will exploit the potential of electronic medical record (EMR) systems, embedding all key aspects of the trial including screening, consent, randomisation and data collection into standard clinical and EMR workflows.

Comprehensive humoral and cellular immune responses to COVID-19 vaccination in adults with cancer.

Background: The COVID-19 pandemic has significantly impacted people with cancer. Initial vaccine studies excluded patients with malignancy. Immunocompromised individuals remain vulnerable to SARS-CoV-2, necessitating detailed understanding of vaccine response.
