Vaccination in immunosuppressed patients with rheumatic diseases requires individualized risk-benefit assessment that accounts for medication-specific immunosuppression levels, vaccine type (live vs non-live), disease activity, lymphocyte counts, immunoglobulin levels, and comorbidities. VAX-SAFE implements a composite weighted scoring system (0-100) grounded in ACR 2022, EULAR 2019, and CDC guidelines to classify vaccine-patient pairs as Safe, Conditional, Caution, High Risk, or Contraindicated. The model incorporates drug-specific immunosuppression grading for 30+ medications including rituximab, JAK inhibitors, and high-dose glucocorticoids, with critical safety logic for live attenuated vaccines. Monte Carlo sensitivity analysis (n=5000 simulations) quantifies score uncertainty under biological variability in lymphocyte counts, IgG levels, and disease activity fluctuations. Timing recommendations follow ACR conditional guidance for methotrexate hold, rituximab B-cell recovery windows, and JAK inhibitor pauses. Demonstrated across three clinical scenarios: RA on combination therapy, lymphopenic SLE on rituximab, and pregnant SLE patient. The executable Python skill produces actionable, guideline-aligned vaccination schedules with per-vaccine safety classifications. Developed by RheumaAI (Frutero Club) for clinical decision support in rheumatology practice.

STORM (Stochastic Therapy Optimization for Rheumatology in Mexico) v3.1 is a pharmacogenomic decision-support calculator implementing ancestry-stratified allele frequency interpolation across 18 genes, 39 drugs, and 11 rheumatic diseases. The computational model integrates published odds ratios from CPIC, PharmGKB, and Mexican pharmacogenomic cohorts with linear ancestry interpolation between European and Indigenous American reference frequencies. Calibration against published Mexican mestizo frequencies yields R²=0.986. Deployed on RheumaScore.xyz with Fully Homomorphic Encryption (FHE), ensuring zero-knowledge clinical computation. This paper presents the mathematical framework, evidence base of 291 publications, and proof-of-concept validation methodology for prospective evaluation in a 607-patient IMSS cohort.
