inclusion difficulties

The main objective is to study the impact of vaccination against Covid-19 on the specific humoral and cellular immune response (against SARS-CoV-2) and non-specific (evolution of the pathological immune system of the disease), in a lupus population.

The secondary objective is to study the impact of lupus disease activity on the humoral and cellular response of patients following vaccination against SARS-CoV-2.

The hypothesis is that disease activity and / or certain treatments used in lupus may interfere with the humoral and cellular immune response induced by vaccination against SARS-CoV-2.
