30 months, multicentre, prospective observational study on adult (>18 years) patients with a diagnosis of rare and complex connective tissue diseases (rCTDs) who will be given the vaccine during the period from January 2021 and January 2022.
Patients with the following diagnosis will be included:
This is an observational study aimed at gathering sufficient number of cases of rCTDs patients who will receive COVID-19 vaccination that will help in better understanding of both safety and efficacy of the vaccine in this population. The study will be promoted both in ERN ReCONNET Full Members and Affiliated Partners as well as in other centres treating and managing rare and complex connective tissue diseases.
