NCT04924855

Brief Summary

The purpose of the research is to evaluate kinetic after vaccination to the COVID-19 coronavirus by measurements of specific and neutralizant antibodies for spike antigenic sequences . This work will allow us to follow the efficacy and tolerance of the vaccine over a year, to evaluate the antibody profile, their kinetics, the fraction of neutralising antibodies and will also allow us to understand the attitudes to be taken to ensure the best protection for our staff
