Overview

In a group of vaccinated and unvaccinated individuals who did or did not experience Covid-19 disease, we monitored the relationship between anti-SARS-CoV-2 IgG and some parameters that, according to the literature, are important in the development and course of illness of Covid-19. These were total IgG, IgG1-4 subclasses, complement components C3c, C4 and circulating immune complexes (CIC). We found that unvaccinated, vaccinated with Pfizer/BioNTech and Moderna vaccine, as well as advanced and non-advanced Covid-19 patients differed significantly in the level of anti-SARS-CoV-2 IgG. Vaccination had a greater effect on the level of antibodies than experiencing the disease. IgG4 increased in vaccinees after the Pfizer/BioNTech vaccine. Other IgG subclasses, total IgG, CIC and complement components were not statistically significantly different between groups.
