COVID-19 Vaccines

Brief summary

Study Population Population with vaccinated with three different Covid Vaccines (Inactive Vaccine (Sinovac Life Sciences, Beijing, China), recombinant human adenovirus serotype number 26 (rAd26 of Sputnik V), mRNA Vaccine (Pfizer/BionTEC). This is multi center study, 5 centers will be joined to study from different part of the country. Approximately 1500 people will be enrolled to study.

Detailed description

Aim of Study * to evaluate Anti-SARS-CoV-2 IgG Antibody and Neutralizing Antibody response in different Vaccine Groups * to evaluate progression of the vaccine response after 2, 6, and 12 Months after Vaccination in different Vaccine Groups, and compare antibody response in different Vaccines Group. * It was also aimed to evaluate effect of the age, gender, co-morbid conditions such as COPD, DM, Heart Failure, Covid Infection on IgG Antibody and Neutralizing Antibody response. Anti SARS CoV2 IgG antibody levels will be measured with chemiluminescence method (CHEM) by using ADVIA Centaur XP Immunassay System (Siemens Helthcare, GmbH, Germany) and Anti SARS CoV2 IgG reactive (Siemens Helthineers, GmbH, Germany). Neutralizing Capacity of Anti-SARS-CoV-2 Antibodies against SARS CoV2 levels will be determined with ELISA method (ELx 808, ELISA Microplate Absorbance Reader, BioTek Instruments Inc, Winooski, VT, USA) by using Euroimmun SARS-CoV-2 NeutraLISA Assay (EUROIMMUN, Medizinische Labordiagnostika AG, Germany).
