Abstract

The BBIBP-CorV severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) inactivated vaccine has been authorized for emergency use and widely distributed. We used single-cell transcriptome sequencing to characterize the dynamics of immune responses to the BBIBP-CorV inactivated vaccine. In addition to the expected induction of humoral immunity, we found that the inactivated vaccine induced multiple, comprehensive immune responses, including significantly increased proportions of CD16[SUP]+[/SUP] monocytes and activation of monocyte antigen presentation pathways; T-cell activation pathway upregulation in CD8[SUP]+[/SUP] T cells, along with increased activation of CD4[SUP]+[/SUP] T cells; significant enhancement of cell-cell communications between innate and adaptive immunity; and the induction of regulatory CD4[SUP]+[/SUP] T cells and co-inhibitory interactions to maintain immune homeostasis after vaccination. Additionally, comparative analysis revealed higher neutralizing antibody levels, distinct expansion of naïve T cells, a shared increased proportion of regulatory CD4[SUP]+[/SUP] T cells, and upregulated expression of functional genes in booster dose recipients with a longer interval after the second vaccination. Our research will support a comprehensive understanding of the systemic immune responses elicited by the BBIBP-CorV inactivated vaccine, which will facilitate the formulation of better vaccination strategies and the design of new vaccines.
