Specific IgA, but Not IgG, in Human Milk from COVID-19-Infected Mothers Neutralizes SARS-CoV-2This study highlights the importance of human milk in providing anti-severe acute respiratory syndrome coronavirus 2 immunity to newborns. The highest protective activity of human milk against COVID-19 was found in colostrum from infected mothers.

Estimating the impact of test–trace–isolate–quarantine systems on SARS-CoV-2 transmission in AustraliaAustralian states and territories used test-trace-isolate-quarantine (TTIQ) systems extensively in their response to the COVID-19 pandemic in 2020-2021. We report on an analysis of Australian case data to estimate the impact of test-trace-isolate-quarantine systems on SARS-CoV-2 transmission.

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.

Opportunities to strengthen respiratory virus surveillance systems in Australia: lessons learned from the COVID-19 responseDisease surveillance data was critical in supporting public health decisions throughout the coronavirus disease 2019 (COVID-19) pandemic. At the same time, the unprecedented circumstances of the pandemic revealed many shortcomings of surveillance systems for viral respiratory pathogens. Strengthening of surveillance systems was identified as a priority for the recently established Australian Centre for Disease Control, which represents a critical opportunity to review pre-pandemic and pandemic surveillance practices, and to decide on future priorities, during both pandemic and inter-pandemic periods.

Global Disparities of Cancer and Its Projected Burden in 2050Cancer prevention and care efforts have been challenged by the COVID-19 pandemic and armed conflicts, resulting in a decline in the global Human Development Index (HDI), particularly in low- and middle-income countries. These challenges and subsequent shifts in health care priorities underscore the need to continuously monitor cancer outcome disparities and statistics globally to ensure delivery of equitable and optimal cancer prevention and care in uncertain times.

Impact of previous exposure to SARS-CoV-2 and of S-Trimer (SCB-2019) COVID-19 vaccination on the risk of reinfection: a randomised, double-blinded, placebo-controlled, phase 2 and 3 trialWe previously reported the efficacy of the adjuvanted-protein COVID-19 vaccine candidate S-Trimer (SCB-2019) in adults who showed no evidence of previous exposure to SARS-CoV-2. In this study, we aimed to investigate the extent of protection afforded by previous exposure to SARS-CoV-2 on subsequent COVID-19 infection, as well as the efficacy, safety, and reactogenicity of SCB-2019 in participants who were enrolled in the Study.

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).

COVID-19 vaccine knowledge, attitudes, and experiences of health care workers in Perth, Western Australia: A qualitative studyHealth care workers (HCWs) faced an increased risk of Coronavirus Disease 2019 (COVID-19). Australia’s COVID-19 vaccine rollout commenced in February 2021 to priority groups, including HCWs. Given their increased risk, as well as influence on patients’ vaccine uptake, it was important that HCWs had a positive COVID-19 vaccination experience, as well as trusting the vaccine safety and efficacy data.

Effects of climatic factors on COVID-19 transmission in EthiopiaClimatic conditions play a key role in the transmission and pathophysiology of respiratory tract infections, either directly or indirectly. However, their impact on the COVID-19 pandemic propagation is yet to be studied.

The short term safety of COVID-19 vaccines in Australia: AusVaxSafety active surveillance, February – August 2021To assess the short term safety of the COVID-19 vaccines Comirnaty (Pfizer–BioNTech BNT162b2) and Vaxzevria (AstraZeneca ChAdOx1) in Australia.
