Abstract

Purpose: This study analyses the immune response of elite athletes after COVID-19 vaccination with double-dose mRNA and a single-dose vector vaccine. Methods: Immunoglobulin G (IgG) antibody titers, neutralizing activity, CD4 and CD8 T-cells were examined in blood samples from 72 athletes before and after vaccination against COVID-19 (56 mRNA (BNT162b2 / mRNA-1273), 16 vector (Ad26.COV.2) vaccines). Side effects and training time loss was also recorded. Results: Induction of IgG antibodies (mRNA : 5702 BAU/ml ; 4343 BAU/ml (hereafter: median), vector: 61 BAU/ml ; 52 BAU/ml, p
