Comprehensive tracking of allergy immunotherapy development including SLIT (sublingual) tablets, SCIT (subcutaneous) allergy shots, peptide vaccines, and next-generation tolerance approaches. Allergies affect 100 million US adults (40%), 400 million globally. Allergic rhinitis (hay fever), asthma, food allergies, and eczema cause significant morbidity and $18 billion annual US costs. Immunotherapy induces immune tolerance to allergens through gradual desensitization, offering long-term symptom relief and potential cure. Multiple FDA-approved SLIT tablets (grass, ragweed, dust mite), injectable SCIT formulations, and novel peptide/recombinant vaccines in development. Disease-modifying treatment changing natural history vs. symptomatic medications. Complementary to environmental control and antihistamines.
Allergies affect 100 million US adults (40%), 400 million globally. Allergic rhinitis (hay fever) most common - 81 million Americans, 1 billion globally. Costs $18 billion annually (medical costs, lost productivity). Food allergies: 32 million Americans (8 million children), anaphylaxis risk 200 deaths/year. Asthma (allergic component 60%): 25 million Americans, 262,000 deaths globally. Eczema/atopic dermatitis: 31 million Americans. Quality of life significantly impaired - sleep disruption, concentration difficulties, embarrassment, anxiety. Current medications (antihistamines, nasal steroids) only control symptoms temporarily. Immunotherapy ONLY treatment that can cure or provide long-lasting remission by retraining immune system.

Scope: 100 million US adults (40%), 400 million globally. Increasing: doubled in 30 years (hygiene hypothesis - reduced microbial exposure in childhood β Th2-skewed immunity). Allergic rhinitis 81M US, asthma 25M US (60% allergic component), food allergies 32M US (8M children), eczema 31M US. Children disproportionately affected - 40% have allergic disease.
Atopic March: Natural progression: eczema in infancy β food allergy toddlerhood β allergic rhinitis school-age β asthma adolescence. Early intervention (immunotherapy for rhinitis) can PREVENT asthma development - major disease-modifying benefit.
Impact: Quality of life severely impaired (worse than many chronic diseases in QOL studies). Sleep disruption, concentration difficulties, school/work absences (4M missed workdays/year). Psychological: anxiety, embarrassment, social isolation (especially food allergies). Financial: $18B annual US costs ($12B direct medical, $6B productivity). Anaphylaxis: 200 deaths/year US (mostly food allergies), 200,000 ER visits. Asthma exacerbations: 1.6M ER visits, 3,600 deaths annually.
Symptomatic Medications (Temporary Relief): Antihistamines (Claritin, Zyrtec, Allegra) - block H1 receptors, 30-40% symptom reduction, side effects (drowsiness with older generations). Nasal steroids (Flonase, Nasacort) - reduce inflammation, 50% improvement, need daily use. Leukotriene inhibitors (Singulair/montelukast) - block inflammatory mediators. Biologics (Xolair/omalizumab for severe asthma/urticaria) - anti-IgE, very expensive ($30,000/year). ALL require continuous use - stop β symptoms return immediately. DO NOT change natural history or prevent disease progression.
Immunotherapy (Disease-Modifying): ONLY treatment that induces lasting remission/cure. Mechanism: Restores immune tolerance rather than suppressing symptoms. Benefits persist years after stopping (vs. medications requiring indefinite use). Prevents: New allergen sensitizations, asthma development (60% reduction), quality of life improvement (70-80% patients). Cost-effective long-term: upfront costs but savings from reduced medications/medical visits over lifetime. Challenge: Requires commitment (3-5 years SCIT, 3 years SLIT), not immediate (takes months), not 100% curative (60-90% improvement not elimination).
Near-Term (2025-2028): Peanut SLIT approval (alternative to Palforzia). Multiple food OIT products (egg, milk, tree nut). Ultra-short course SCIT widespread (Pollinex Quattro type - 4-8 injections). Peptide immunotherapy approval for cat/grass (revolution - 8 injections cures allergy). Combination SLIT tablets (multi-allergen single pill - dust mite + grass + cat). EPIT patch reformulation approval (peanut, milk). More biologics (dupilumab/Dupixent for multiple allergic conditions).
Mid-Term (2028-2035): mRNA allergy vaccines (rapid production, customizable, hypoallergenic). ILIT mainstream (3 injections in lymph nodes = cure). Nanoparticle tolerance induction (single injection, sustained release). Preventive immunotherapy (infants high-risk for atopy - prevent allergies before onset). Microbiome interventions + immunotherapy synergy. Combination anti-IgE + rapid desensitization protocols (safe 1-month courses). Personalized immunotherapy (biomarker-guided - who will respond, optimal dose/duration). Gene therapy targeting IgE production (experimental but promising).
Vision: Allergy cure becomes routine - 6-12 month treatment, lifetime remission. Children vaccinated against common allergens preventively. Food allergies no longer life-threatening - desensitization standard. Severe asthma rare (early intervention prevents). Anaphylaxis deaths eliminated. $18B burden reduced to <$5B. Allergies transition from chronic limitation to brief treatable condition like strep throat - inconvenient but curable.
