Objective: To know the behavior of anti-SARS-CoV-2 IgG antibodies before and after vaccination in workers of a cancer center.
Methods: Prior to the application of the vaccine, the presence of anti-SARS-CoV-2 IgG antibodies (n = 171) was analyzed by evaluating anti-N IgG antibodies; post-vaccination, after receiving the second dose, anti-S IgG antibodies were evaluated (n = 60).
