608 SARS-CoV-2 vaccine safety and side effects in people with SLE
Bibliographic record
Abstract
Background People with SLE (and their doctors) are concerned about the risk of COVID-19 infection, yet some patients still harbor concerns regarding vaccination. The first mRNA SARS-CoV-2 vaccines were not studied in this population.1, 2 To address this knowledge gap, we evaluated the safety and side effects of mRNA SARS-CoV-2 vaccines in people with SLE. Methods At a Canadian tertiary care centre, we studied SLE cohort patients who were followed with standardized annual assessments. From January 2021 to May 2022, 345 SLE patients consecutively seen for their annual research visit reported information on SARS-CoV-2 vaccinations. We performed descriptive data analysis on the type of vaccination received, side effects, ER visits, and hospitalizations. Result The patients were mostly female (n=306, 88.7%) and Caucasian (n=209, 60.6%) and the average SLE duration was 19.7 years (SD 11.9). Most patients (n=298, 86.4%) had received at least one SARS- CoV-2 vaccination and 248 (71.9%) has received at least 2 doses. Specifically, 50 (14.5%) had received one dose, 150 (43.5%) had received 2 doses and 98 (28.4%) had received at least 3. Most (n=181, 60.7%) of initial doses were Pfizer, followed by Moderna (n=54, 18.1%), AstraZeneca (n=12, 4.0%) and Johnson & Johnson (n=1, 0.3%). (The remaining (n=50, 16.8%) were unknown type.) About two-thirds (n=159, 63.3%) of the second doses were Pfizer, and 49 (19.5%) were Moderna. Among those receiving at least 1 vaccination dose, 34 of 128 patients who responded to the question reported symptoms post-vaccine (26.6%). The most common symptoms were fever and injection- related arm pain; both were reported at equal frequency (n=9, 7.0%). Other symptoms were fatigue and headache (n=6, 4.6% for both). There were 3 cases of myalgia and 2 cases of arthralgia. One patient reported hypertension after the first dose of vaccine which required a short 24h ER visit. The remaining did not specify their symptoms. No patients reported disease flare in the post vaccination period. Amongst those who provided information about SARS-CoV-2 infection (n=243), 19.3% reported testing positive for SARS-CoV-2. Only one patient required hospitalization for SARS-CoV-2 infection and was vaccine naïve at the time. Conclusion SARS-CoV-2 mRNA vaccine side effects in this SLE population were reported in about a quarter of subjects but symptoms were mild, similar to reports in the general population. We did not detect any side effects requiring hospitalization. Since, in our cohort, the one subject requiring hospitalization for SARS-CoV-2 infection was vaccine-naïve, a benefit for SARS-CoV-2 vaccination in SLE seems evident.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
