COVID-19 Vaccination, Hospitalization Rates, and Mortality Differ Between People with Diagnosed Immune Mediated Inflammatory Disease and the General Population: A Population-Based Study.

ABSTRACT:

Background

Vaccination reduces Coronavirus disease-19 (COVID-19) infection severity. We evaluated COVID-19 vaccine uptake and effectiveness in people with immune mediated inflammatory diseases (pIMIDs) versus the general population.

Methods

Using population-based administrative health records, we identified cohorts between 2004 and 2022 with an IMID (rheumatoid arthritis n = 10,405, systemic autoimmune rheumatic disease n = 5888, inflammatory bowel disease n = 7911, multiple sclerosis n = 3665, psoriasis n = 23,948) who were matched (1:5) by age, sex, and region to general population comparators (n = 243,490) without these IMIDs. Between 1 January 2021 and 31 March 2022, rates of COVID-19 vaccine administration, hospitalizations with
