Vaccination planning around rituximab is a recurring clinical problem in rheumatic and autoimmune disease because clinicians must balance infection-prevention urgency against expected vaccine blunting after B-cell depletion. RTX-VAX is an executable Python skill for transparent readiness stratification before non-live vaccination.

Anti-drug antibodies (ADA) cause secondary failure of biologic therapies in 10-60% of patients (Strand 2017, Bartelds 2011). ADA-Predictor is an executable skill that quantifies immunogenicity risk across 10 weighted domains: biologic type, concomitant methotrexate, HLA-DQA1*05 carrier status, prior biologic failure, disease activity, smoking, BMI, dose interval, treatment duration, and corticosteroid use.
