    Robust and Prototypical Immune Responses toward COVID-19 Vaccine in First Nations Peoples Are Impacted by Comorbidities

    Reduced receptor-binding domain antibodies, spike-specific B cell,s and follicular helper T cells were found in vaccinated participants with chronic conditions and were strongly associated with altered glycosylation of IgG and increased interleukin-18 levels in the plasma.
