Detailed description

AIGI (Adaptive Immune Response to Seasonal Influenza Vaccination) is a prospective clinical study aiming at elucidating the kinetics of vaccine-specific antibody production after seasonal Influenza vaccination in health care workers at the Greifswald University hospital. Participants were recruited before their intended vaccination. Participants received the influenza vaccine Vaxigrip Tetra 2020/2021 by Sanofi Pasteur Europe. Within the study, volunteers donate peripheral blood by venipuncture on the day of vaccination as well as 7 and 14 days after vaccination. EDTA plasma and peripheral mononuclear cells (PBMCs) are prepared and stored at -20 °C. Volunteers are also asked to complete a standardized questionnaire on each day of blood sampling. Questionnaires collect data about physical characteristics, seasonal influenza vaccinations, current infections, medication, immune relevant diseases and side effects of the vaccination.
