NCT05353738

Brief Summary

Des vaccins sont désormais disponibles en France, dont le vaccin Moderna COVID-19 qui est basé sur la technologie des ARNm. La séquence génétique qu'il contient code pour la protéine Spike (S) de l'enveloppe virale, protéine clé de la pénétration du virus dans les cellules qu'il infecte. Le vaccin ARNm est injecté par voie intramusculaire et pénètre dans les fibres musculaires, qui sont des cellules produisant des protéines en très grande quantité en continu, notamment pour la production de myofibrilles impliquées dans la contraction musculaire. Une fois à l'intérieur de la fibre musculaire, l'ARNm vaccinal est traduit par la machinerie de la fibre musculaire permettant une grande quantité de protéine Spike (S) qui sera présentée au système immunitaire provoquant la réponse vaccinale et notamment les anticorps neutralisants anti-S (NAb). Ces NAb anti-S agissent en perturbant l'interaction entre la protéine S du virus et le récepteur ACE2 (Angiotensin-Converting Enzyme 2), qui sert généralement de " passerelle " entre le virus et la cellule. Une campagne de vaccination est actuellement en cours au MAS-YDK avec le vaccin Moderna. Cette population est donc relativement homogène en termes d'amyotrophie, de non exposition au SARS-CoV-2 et de protocole vaccinal.

Outcome Measures

Primary Outcomes (1)

  • Look for the presence of antibodies anti-Spike neutralizers, 6 weeks after the second injection of the vaccine Moderna against COVID-19 in patients with severe amyotrophy in MAS Yolaine de Kepper.

    The presence of Ac causing the neutralization of the interaction between the viral protein S and the receptor ACE-2 cells by the syncytia formation inhibition assay.

    6 weeks after the second injection of the Moderna vaccine

Secondary Outcomes (7)

  • Confirm the presence of anti-Spike neutralizing antibodies, 6 weeks after the second injection of the Moderna vaccine against COVID-19 by another technique:

    6 week after the second injection of Moderna vaccine

  • Look for the presence of anti-Spike neutralizing antibodies, 24 weeks after the second injection of the Moderna vaccine against COVID-19

    24 week after the second injection of the Moderna vaccine against

  • Look for the presence of neutralizing antibodies to Spike, 52 or 64 weeks after the second injection of the Moderna vaccine against COVID-19 (i.e. approximately 6 months or 9 months after the 3rd dose of reminder)

    52 or 64 week after the second injection of the Moderna vaccine

  • Look for the presence of neutralizing antibodies directed against most recent delta and omicron variants, at all times of study

    Throughout study completion, an average 64 week

  • Assessing the effectiveness of vaccination in real life

    Throughout study completion, an average 64 week

  • +2 more secondary outcomes

Study Arms (3)

Patients with severe neuromuscular disease

Patient with severe neuromuscular disease and having received vaccination with the Moderna vaccine

Biological: Blood sample for research of anti-xoprs netralizing anti spikeOther: Questionnaire

Patients groupe témoins négatif

Patient having had a blood sample taken as part of the treatment for virological analysis before anti-COVID 19 vaccination

Biological: Blood sample for research of anti-xoprs netralizing anti spike

Patients groupe témoins positif

Patient having had a blood sample taken as part of the treatment for virological analysis following infection with the omicron variant.

Biological: Blood sample for research of anti-xoprs netralizing anti spike

Interventions

The evaluation of the ex vivo efficacy of the Moderna vaccine by the search for anti Spike AcN at 6,24, 40 and 52 or 64 weeks after the second injection of the vaccine. The effectiveness of vaccination of CANNEMUSS patients will be evaluated by comparing the antibodies anti-S neutralizers from patients in the CANNEMUSS study to those from patients whose sample was carried out before the pandemic (negative control group) and those of patients infected with the omicron virus (positive control group).
