Humoral and cellular responses to SARS‐CoV‐2 variants after ancestral COVID‐19 vaccines in people with HIV and lung transplant recipients
Abstract Objectives Immunocompromised hosts have reduced immune responses to COVID‐19 vaccination, and more severe disease. Antibody responses correlate with protection but markers of immunity vary across a spectrum of immunocompromise. We compared serologic and cellular responses following Ancestral COVID‐19 vaccines...
