Indigenous peoples globally are at increased risk of COVID-19-associated morbidity and mortality. However, data that describe immune responses to SARS-CoV-2 infection in Indigenous populations are lacking. We evaluated immune responses in Australian First Nations peoples hospitalized with COVID-19. Our work comprehensively mapped out inflammatory, humoral and adaptive immune responses following SARS-CoV-2 infection. Patients were recruited early following the lifting of strict public health measures in the Northern Territory, Australia, between November 2021 and May 2022. Australian First Nations peoples recovering from COVID-19 showed increased levels of MCP-1 and IL-8 cytokines, IgG-antibodies against Delta-RBD and memory SARS-CoV-2-specific T cell responses prior to hospital discharge in comparison with hospital admission, with resolution of hyperactivated HLA-DR + CD38 + T cells. SARS-CoV-2 infection elicited coordinated ASC, Tfh and CD8 + T cell responses in concert with CD4 + T cell responses. Delta and Omicron RBD-IgG, as well as Ancestral N-IgG antibodies, strongly correlated with Ancestral RBD-IgG antibodies and Spike-specific memory B cells. We provide evidence of broad and robust immune responses following SARS-CoV-2 infection in Indigenous peoples, resembling those of non-Indigenous COVID-19 hospitalized patients., (© 2023 The Authors.

High-risk groups, including Indigenous people, are at risk of severe COVID-19. Here we found that Australian First Nations peoples elicit effective immune responses to COVID-19 BNT162b2 vaccination, including neutralizing antibodies, receptor-binding domain (RBD) antibodies, SARS-CoV-2 spike-specific B cells, and CD4 + and CD8 + T cells. In First Nations participants, RBD IgG antibody titers were correlated with body mass index and negatively correlated with age. Reduced RBD antibodies, spike-specific B cells and follicular helper T cells were found in vaccinated participants with chronic conditions (diabetes, renal disease) and were strongly associated with altered glycosylation of IgG and increased interleukin-18 levels in the plasma. These immune perturbations were also found in non-Indigenous people with comorbidities, indicating that they were related to comorbidities rather than ethnicity. However, our study is of a great importance to First Nations peoples who have disproportionate rates of chronic comorbidities and provides evidence of robust immune responses after COVID-19 vaccination in Indigenous people., (© 2023.

Background: Pandemics such as COVID-19 are a serious public health risk for Australian Aboriginal and Torres Strait Islander communities, yet primary healthcare systems are not well resourced to respond to such urgent events. At the start of the COVID-19 pandemic, a federal government advisory group recommended a rapid, tailored Indigenous response to prevent predicted high morbidity and mortality rates. This paper examines the efforts of one ACCHO, which in the absence of dedicated funding, pivoted its operations in response to COVID-19. Gurriny Yealamucka Health Service (Gurriny) is the only primary healthcare service in the discrete Indigenous community of Yarrabah, Far North Queensland., Methods: The research was conducted at the request of the Chief Executive Officer of Gurriny. Using grounded theory methods, thirteen Gurriny staff and five Yarrabah and government leaders and community members were interviewed, transcripts of these interviews and 59 documents were imported into NVIVO-12 and coded, and key concepts were compared, organised into higher order constructs, then structured into a theoretical framework., Results: Gurriny responded to COVID-19 by leading with local solutions to keep Yarrabah safe. Four key strategies were implemented: managing the health service operations, realigning services, educating and supporting community, and working across agencies. These strategies were enabled or hindered by five conditions: the governance and leadership capacity of Gurriny, relying on the health taskforce, locking the door, "copping it", and (not) having resources. A year after the first case was experienced in Australia and on the eve of vaccine rollout to Indigenous communities, there have been no COVID-19 cases in Yarrabah., Discussion: The success of the locally led, holistic, comprehensive and culturally safe response of Gurriny suggests that such tailored place-based approaches to pandemics (and other health issues) are appropriate, but require dedicated resourcing. Key challenges were the fragmented and rapidly changing government processes, poorly coordinated communication and resource allocation channels, and bottlenecks in hierarchical funding approval processes., Conclusions: The COVID-19 response in Yarrabah demonstrates the need for governance reform towards greater resourcing and support for local decision making by Aboriginal community-controlled health organisations., (© 2021.

Faith communities are uniquely positioned for essential public health work to combat the COVID-19 pandemic and address the chronic pre-existing health disparities that have been exacerbated by COVID-19. Specifically, faith communities can (1) dialogue with public health communities, developing internal policies and meeting guidelines consistent with evidence-based recommendations and their own faith traditions, (2) bolster religious daycare and parochial school immunization policies, and (3) partner with faith-based organizations through financial support and volunteer hours. This essential work will complement governmental public health approaches and ensure faith communities can assist with future pandemics.
