Abstract

The immune response generated by SARS-CoV-2 vaccination protocols and natural infection remains incompletely understood. We compared individuals who received a heterologous vaccination scheme with a booster shot (vaccine immunity) to those who experienced a mild COVID-19 episode (hybrid immunity) during the same timeframe. Our findings revealed similar levels of SARS-CoV-2 antibodies in both groups. Stimulation by viral antigen in mononuclear cell cultures induced pro-inflammatory cytokines in both groups, while individuals with vaccine immunity exhibited lower IL-17. These results suggest that a vaccine booster can induce an immune response in previously vaccinated individuals comparable to that elicited by natural SARS-CoV-2 infection.
