DANTE-SIRIO 7: Determinants of the Level of Anti-SARS-CoV-2 IgG ANTibodiEs After Vaccination Study
Study Details
Study Description
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. We have designed the study assessing the anti-SARS-CoV-2 IgG antibody titer after vaccination cycle 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

Detailed Description
The study includes healthy, unselected volunteers from the staff of Antoni Jurasz University Hospital No.1 in Bydgoszcz and students of Collegium Medicum, Nicolaus Copernicus University. To meet the inclusion criteria patients will have to be vaccinated with two doses of the BNT162b2 vaccine. The assessment of the anti-SARS-CoV-2 IgG antibody titer at several time points in each participant. Fresh serum samples were used to measure SARS-CoV-2 IgG on the Siemens Atellica system (Siemens Healthineers, Erlangen, Germany). Results of SARS-CoV-2 IgG were given as U/ml, whereby the cut-off for positivity was defined as ≥1.0 U/ml.

Outcome Measures
Primary Outcome Measures
- the anti-SARS-CoV-2 IgG antibody concentration 3 months after vaccination cycle with the BNT162b2 vaccine [0-12 months]
evaluation of anti-SARS-CoV-2 IgG antibody concentration 3 months after 2-dose vaccination with BNT162b2 vaccine
Secondary Outcome Measures
- the anti-SARS-CoV-2 IgG antibody concentration 6, 9 and 12 months after two-dose vaccination cycle [0-12 months]
evaluation of anti-SARS-CoV-2 IgG antibody concentration at particular time points in 2-dose vaccination schedule
- the anti-SARS-CoV-2 IgG antibody concentration immediately before, 1 and 3 months after the third vaccine dose [0-12 months]
evaluation of anti-SARS-CoV-2 IgG antibody concentration at particular time points after 3rd dose of vaccine
- local and/or systemic adverse reactions after vaccination [0-12 months]
verification of any adverse events occurrence based on survey filled by participants on each visit
- confirmed COVID-19 after vaccination [0-12 months]
verification of COVID-19 based on survey filled by participants on each visit
