Summary

Vaccination against COVID-19 is a major public health issue to control the epidemic and reduce the number of severe infections and deaths. Three vaccines currently received use authorization in France: two mRNA vaccines and one recombinant viral vector vaccine. Immunogenicity data demonstrate that they induce the development of neutralizing antibodies and IgG directed against the viral S1 protein and the receptor binding domain (RBD). However, there are currently no data on the persistence over time of the humoral response induced by vaccination, and data are still incomplete on cellular immunogenicity. No immune correlate of protection has been established for COVID-19.

In addition, these data come from assays carried out with current vaccines developed against a lineage of SARS-CoV-2 known as wild type (without genetic mutations).

The main objective of this study is to monitor in hospital staff the temporal evolution of humoral immunity induced by anti-COVID-19 vaccines by using enzyme-linked immunosorbent assays (ELISA), at 3, 6, 12 and 24 months after the last injection of vaccine.
