NCT05162456

Brief Summary

Great expectations to control the pandemic are placed in vaccines against COVID-19. Currently, the four COVID-19 vaccines approved in the European Union. The investigators designed a study assessing the anti-SARS-CoV-2 IgG antibody titer after vaccination cycle with the BNT162b2 vaccine in several time points relating these results to the COVID-19 history and severity of symptoms during the disease and after the first and second vaccine dose.
