Cellular immune response was measured via the SARS-CoV-2 inSIGHT™ T-cell immunity panel. The overall response (detected/not detected) was further categorized into CD4 and CD8 response. Samples (n = 37) were obtained after 2-doses of the vaccine (Visit 1) and after the 3rd vaccine dose (Visit 2). The proportion of participants with positive/negative results are displayed within the graph.
