mRNA Vaccine-Induced SARS-CoV-2 Spike-Specific IFN-γ and IL-2 T-cell Responses are Predictive of Serological Neutralization and are Transiently Enhanced by Pre-Existing Cross-Reactive Immunity

This study examines how mRNA vaccine-induced T-cell responses correlate with neutralizing antibodies and how pre-existing immunity affects vaccine responses over time.

Immunogenicity of COVID-19 vaccines and their effect on the HIV reservoir in older people with HIV

This study evaluates the immunogenicity of COVID-19 vaccines in older people with HIV and their impact on HIV reservoirs, finding that three doses are needed for optimal neutralizing responses but vaccines may increase HIV reservoirs in those with persistent viremia.

Longitudinal Assessment of SARS-CoV-2 Specific T Cell Cytokine-Producing Responses for 1 Year Reveals Persistence of Multi-Cytokine Proliferative Responses, with Greater Immunity Associated with Disease Severity

This study tracks SARS-CoV-2-specific T cell cytokine responses over one year, finding persistent multi-cytokine production with greater immunity linked to disease severity.
