Multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposures, from infection or vaccination, can potently boost spike antibody responses. Less is known about the impact of repeated exposures on T cell responses. Here, we compare the prevalence and frequency of peripheral SARS-CoV-2-specific T cell and immunoglobulin G (IgG) responses in 190 individuals with complex SARS-CoV-2 exposure histories. As expected, an increasing number of SARS-CoV-2 spike exposures significantly enhances the magnitude of IgG responses, while repeated exposures improve the number of T cell responders but have less impact on SARS-CoV-2 spike-specific T cell frequencies in the circulation. Moreover, we find that the number and nature of exposures (rather than the order of infection and vaccination) shape the spike immune response, with spike-specific CD4 T cells displaying a greater polyfunctional potential following hybrid immunity compared with vaccination only. Characterizing adaptive immunity from an evolving viral and immunological landscape may inform vaccine strategies to elicit optimal immunity as the pandemic progress. Repeated SARS-CoV-2 spike exposures enhance IgG responses Repeated spike exposures do not enhance the frequency of spike T cell responses The proportion of T cell responders reaches a plateau after three exposures Hybrid immunity induces more polyfunctional spike CD4 cells than vaccination only Keeton et al. investigate the effect of multiple exposures to SARS-CoV-2 spike (through infection and/or vaccination) on T cell and IgG responses. They show that an increasing number of exposures enhances the magnitude of IgG responses but has no major impact on the magnitude of SARS-CoV-2 spike-specific T cells.
