“…Breakthrough infections were higher (7.4%) in our study as Kerala (a state in Southern India) was facing the second wave due to delta variant during this period when the study was conducted 13. There are two studies, one each from Europe and the United States, which reported lower breakthrough infections (<1%, 4.7%, respectively) in patients with AIRD postvaccination 8 9. They had a similar patient profile with the most common disease subtype being RA.…”

“…Data from two large European registries showed a breakthrough rate of less than 1% from all patients with AIRD and a single centre American study found this to be 4.7%. However, breakthrough infection was associated with a much higher risk of death (8%–13%) and post-COVID-19 sequelae (8%) 8 9. Thus, it is of utmost importance to identify and mitigate risk factors for breakthrough infections.…”

“…Strategies to rescue the immunogenicity in these patients by repeating a full vaccine course [32] or giving a third dose [33] might be explored in larger studies. Peripheral lymphocytes subpopulations (especially CD19 + counts > 27 cells/μL) are predictive of vaccine response and there is a short period observed from vaccine to infection [34,35], that may indicate the importance of detecting primary non-responders. These findings preliminary suggest that patients treated with anti-CD20 may deserve attention on B-cell reconstitution and/or antibody testing and strict adherence to personal protective measures.…”

“…While patients with IMIDs on BCDTs have been recognized to be vulnerable to severe COVID-19 infections, 3,4,6,7 relatively scant data exist regarding their risks for and outcomes of breakthrough infections 2,18 . The current cohort of breakthrough patients consisted of nearly equal numbers of patients with rheumatic and neuro-inflammatory disease and most (91.9%) were either fully vaccinated or boosted, with only 6 (8.1%) with incomplete vaccination.…”
