Effect of Bacille Calmette-Guérin vaccination on immune responses to SARS-CoV-2 and COVID-19 vaccination.

Objectives: Bacille Calmette-Guérin (BCG) vaccination has off-target effects on disease risk for unrelated infections and immune responses to vaccines. This study aimed to determine the immunomodulatory effects of BCG vaccination on immune responses to vaccines against SARS-CoV-2.

Methods: Blood samples, from a subset of 275 SARS-CoV-2-naïve healthcare workers randomised to BCG vaccination (BCG group) or no BCG vaccination (Control group) in the BRACE trial, were collected before and 28 days after the primary course (two doses) of ChAdOx1-S (Oxford-AstraZeneca) or BNT162b2 (Pfizer-BioNTech) vaccination.

Drug-resistant tuberculosis: integrative review of nursing care in primary health care.

Objectives: to identify, in the scientific literature, the care that should be provided to individuals with drug-resistant tuberculosis by nurses in primary health care.

Methods: integrative review, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses study selection flowchart. Data collection was conducted in November 2022, across ten databases.

Advancing integrated paediatric care in Australian general practices: Qualitative insights from the SC4C GP-paediatrician model of care.

The Strengthening Care for Children (SC4C) is a general practitioner (GP)-paediatrician integrated model of care that consists of co-consulting sessions and case discussions in the general practice setting, with email and telephone support provided by paediatricians to GPs during weekdays. This model was implemented in 21 general practices in Australia (11 Victoria and 10 New South Wales). Our study aimed to identify the factors moderating the implementation of SC4C from the perspectives of GPs, general practice personnel, paediatricians and families.

The influence of neonatal BCG vaccination on in vitro cytokine responses to Plasmodium falciparum.

Background: Bacillus Calmette-Guérin (BCG) vaccination has off-target protective effects against infections unrelated to tuberculosis. Among these, murine and human studies suggest that BCG vaccination may protect against malaria. We investigated whether BCG vaccination influences neonatal in vitro cytokine responses to Plasmodium falciparum.

Specific and off-target immune responses following COVID-19 vaccination with ChAdOx1-S and BNT162b2 vaccines-an exploratory sub-study of the BRACE trial.

Background: The COVID-19 pandemic led to the rapid development and deployment of several highly effective vaccines against SARS-CoV-2. Recent studies suggest that these vaccines may also have off-target effects on the immune system. We sought to determine and compare the off-target effects of the adenovirus vector ChAdOx1-S (Oxford-AstraZeneca) and modified mRNA BNT162b2 (Pfizer-BioNTech) vaccines on immune responses to unrelated pathogens.
