About

The frequency of severe forms of COVID-19 is higher in people with neuromuscular disease and in severe cases and long hospital stays, the disability of some neuromuscular patients may worsen due to prolonged bed rest . Finally, the symptoms of certain diseases such as myasthenia gravis can worsen after an infection such as COVID-19.

Thanks to an unprecedented research effort, vaccines are now available and others still in development. The first studies published in medical journals are reassuring about the efficacy and safety of these vaccines. However, they have been studied in the general population and we do not yet have specific information in neuromuscular patients.

This is the reason why the Va-C-NEMUS observatory was launched.

Full description

Prevention of COVID-19 in neuromuscular patients is therefore fundamental and vaccination is eagerly awaited by patients and their healthcare teams. An unprecedented research effort has made it possible to create vaccines in a very short time when no vaccine directed against a coronavirus has existed until now. Some of these vaccines are based on proven technologies while others such as RNA vaccines are very innovative. The results of the phase III studies of 3 of them have just been published (Pfizer/BioNTech, Moderna and Astra-Zeneca). Among them, the Pfizer-BioNTech and Moderna vaccines have received authorization for use from the European Medicines Agency. The data on the individuals enrolled in these trials are still not very detailed. However, we already know that in the Pfizer/BioNTech trial, patients on immunosuppressants were excluded. For the Astra-Zeneca vaccine, the publication combines data from 4 different trials. In two of them the patients had to be in "good health". In any case, we do not know the pathologies presented by patients outside the usual risk factors for the severe form of COVID-19 (age, obesity, cardiovascular diseases, respiratory diseases). No data on neuromuscular patients are currently known. The vaccination campaign began in France in January 2021. The first neuromuscular patients should be vaccinated soon depending on their comorbidities, but many questions arise in these patients both in terms of safety and efficacy.
