Why do this research?
This study was done to evaluate the safety and effectiveness of two doses of a mRNA-based SARS-CoV2 vaccine (Moderna) in people with a rheumatic disease. Vaccines stimulate the production of antibodies which help protect people from infectious diseases like COVID-19. People with rheumatic disease like rheumatoid arthritis (RA) and systemic Lupus Erythematosus (SLE) often have impaired immune responses that may result from their disease itself or from the medications they need to control their disease. This impairment of their immune system may decrease their bodies’ ability to form antibodies to vaccines or maintain those antibodies long term. If that occurs, they may have a lower level of protection from the vaccine. Also, It is important to determine whether a mRNA vaccine can cause a flare up of symptoms of a rheumatic disease.
What will be done?
This research study recruited 220 participants (165 patients with a rheumatic disease and 55 healthy controls) aged 18 years or older. Participants received two doses from a mRNA vaccine, Moderna, which is one of the vaccines approved by Health Canada. The time between the two doses was 28 days. Evaluation will include determining their anti-COVID-19 response and adverse effects post-vaccination.
Who is involved?
Adults, diagnosed with RA or SLE, on stable treatment and who receive rheumatology care at University of Laval (Quebec City) or at McGill University Health Centre (Montreal) were eligible for the study. Recruitment of specific groups of patients based on age (above and below 65 years of age), and treatment (SLE on mofetil mycophenolate, RA on methotrexate, non-rituximab biologics, rituximab or small molecules) was done. The results of this study will have implications on the decision to make in the near future about whether patients with RA and SLE need special attention at the time of their anti-COVID-19 vaccination.
