The humoral response of the COVID-19 vaccine varies from person to person. It largely depends on prior SARS-
CoV-2 infection, obtaining an adequate immune response, and leaving a trace of changing antibody concentration
over time. We retrospectively analyzed five clinical cases from selected patients and employees of the oncology
hospital. All mild COVID-19 convalescents received the BNT162b2-Comirnaty mRNA vaccine three or four times.
The levels of SARS-CoV-2 IgM- and IgG-specific antibodies, as well as S-RBD antibodies, were analyzed for two years.
The concentration of antibodies was assessed in the laboratory using the chemiluminescent immunoassay CLIA,
MAGLUMI.
Results: (1) Active autoimmune disease stabilized the level of IgG-specific antibodies after systemic mRNA vaccination
for at least six months. (2) Post-vaccination IgG and S-RB.. View More»
