Covid19 Clinical Trial
Official title:
Immunological Responses After Vaccination for COVID-19 With the Messenger Ribonucleic Acid (mRNA) Vaccine Comirnaty in Immunosuppressed and Immunocompetent Individuals. An Open and Non-randomized, Phase IV Multicenter Study
The study is designed as an open, non-randomized, phase IV cohort study in which the mRNA vaccine Comirnaty will be given in two doses. Analyses will be performed on blood and saliva, investigating humoral and cellular vaccine responses. Occurence of local or systemic reactogenicity will be evaluated, as well as adverse events. The study will include persons with primary or secondary immunosuppressive disorders, as well as immunocompetent persons, with the aim of investigating if the immune responses after given Comirnaty mRNA vaccine against COVID-19.
In this study with 450 patients with primary or secondary immunosuppressive disorders (patients with primary immunodeficiency, HIV infected patients, patients with allogenic stem cell transplantation/CAR T cell treated, solid organ transplanted, and patients with chronic lymphatic leukemia) from Karolinska University Hospital, and healthy controls of 90 individuals for comparison, we will investigate the safety and the immune responses after mRNA vaccination with Comirnaty after two doses, under 6 months of time for each participant. The study is In collaboration with research groups at Karolinska Institutet and SciLifeLab, with planned in-depth detailed analyses of antibody responses as well as cellular responses. The study has obtained permission from Swedish Medical Agency and Swedish Ethical Review Authority. ;
