Allergy Vaccine Name: Why SCIT Has None, and the Four SLIT Brand Names
SCIT (the injection-based 'allergy vaccine') has no brand name — it's custom-mixed allergen extract from FDA-licensed manufacturers. SLIT (sublingual) has four FDA-approved brands: Grastek (grass), Oralair (5-grass), Ragwitek (ragweed), Odactra (dust mite). The WHO 1998 position paper (PMID 9802362) endorsed 'allergen vaccine' as the category term.

There is no brand-name SCIT (injection allergy shot) product. Custom-mixed from Greer, ALK-Abelló, or HollisterStier. Four branded SLIT tablet names: Grastek (Timothy grass), Oralair (5-grass mix), Ragwitek (short ragweed), Odactra (house dust mite).
Why 'Allergy Vaccine' Has No One Brand Name — and Four Names for the Sublingual Version
When patients search for 'allergy vaccine name,' they often expect a single branded product — the allergy equivalent of Lipitor or Humira. The answer splits into two depending on delivery route.
For subcutaneous immunotherapy (SCIT — the injectable 'allergy shot'), there is no branded finished-drug product on the US market. Allergen extracts are custom-mixed in the allergist's office from starting material supplied by FDA-licensed manufacturers: Greer Laboratories (now Stallergenes Greer), ALK-Abelló, and Hollister-Stier (Jubilant HollisterStier). The physician selects specific allergens based on the patient's sensitization profile, mixes them to prescription concentrations, and dispenses them in multi-dose vials. There is no 'Greer SCIT' or 'ALK allergy vaccine' with a product name — extracts are raw material, not finished drugs. They are regulated by FDA CBER (Center for Biologics Evaluation and Research), not CDER (drugs).
This no-brand-name reality is exactly how Curex's allergy shot works: a personalized SCIT serum, sterile-compounded to USP <797> standards and matched to your actual IgE results, then self-administered as one weekly shot at home for $129/month rather than dispensed as a branded vial. Curex pairs at-home IgE testing with board-certified allergist review to identify whether a patient's sensitization profile matches an FDA-approved SLIT tablet (grass, ragweed, dust mite) or is suited to this at-home subcutaneous immunotherapy for unmatched allergens like cat dander or tree pollen — with an epinephrine auto-injector prescribed and confirmed on hand and the first dose and every dose change supervised live over Zoom.
For sublingual immunotherapy (SLIT), four FDA-approved tablet products DO have brand names: Grastek (Timothy grass, Phleum pratense; Merck under license from ALK-Abelló), Oralair (5-grass mix including Sweet Vernal, Orchard, Perennial Rye, Timothy, and Kentucky Blue; Stallergenes Greer), Ragwitek (short ragweed, Ambrosia artemisiifolia; Merck), and Odactra (house dust mite, Dermatophagoides farinae and D. pteronyssinus; Merck under license from ALK-Abelló). All four are daily dissolving tablets, not injections. All carry boxed warnings for anaphylaxis and require a supervised first dose with an epinephrine auto-injector prescription.
SCIT: no brand name, custom-mixed from Greer/ALK/HollisterStier. SLIT tablets: four brands — Grastek, Oralair, Ragwitek, Odactra.
The Four SLIT Brand Names — What Each Covers and What It Doesn't
Understanding which FDA-approved SLIT product matches a patient's sensitization requires knowing each product's allergen scope. None of the four covers cat dander, mold, dog dander, or tree pollen — allergens that account for a large proportion of sensitized patients.
Merck, under license from ALK-Abelló. FDA-approved for ages 5–65. Allergic rhinitis with or without conjunctivitis, with or without asthma, caused by Timothy grass. Single-grass product. Build-up begins 4 months before grass season.
Stallergenes Greer. FDA-approved for ages 5–65. Contains Sweet Vernal (Anthoxanthum odoratum), Orchard (Dactylis glomerata), Perennial Rye (Lolium perenne), Timothy (Phleum pratense), and Kentucky Blue (Poa pratensis) grass extracts. Pre-seasonal initiation required.
Merck. FDA-approved, age 5+ since 2021. Single allergen: short ragweed. Must be initiated 4 months before ragweed season. Does NOT cover other ragweed species or mugwort.

There is no branded SCIT product because Curex's allergy shot is personalized: a SCIT serum sterile-compounded to USP <797> standards and matched to your actual IgE results, then self-administered as one weekly shot at home for $129/month. A board-certified allergist confirms candidacy and prescribes the extract, an epinephrine auto-injector is prescribed and confirmed on hand before the first dose, and your first injection and every dose change are supervised live over Zoom — covering allergens like cat dander, tree pollen, and mold that no FDA-branded tablet reaches.

What is the brand name of allergy shots?
Allergy shots (SCIT) have no brand name. The allergen extract is custom-mixed by your allergist from FDA-licensed manufacturer starting materials — Greer Laboratories (Stallergenes Greer), ALK-Abelló, or Hollister-Stier. There is no branded finished-drug SCIT product available at a pharmacy.
What are the four brand names for allergy SLIT tablets?
Grastek (Timothy grass), Oralair (5-grass mix), Ragwitek (short ragweed), and Odactra (house dust mite). All four are daily dissolving sublingual tablets, not injections, approved by FDA as finished drug products.
What does the WHO 1998 position paper say about 'allergy vaccine' terminology?
The 1998 WHO position paper by Bousquet, Lockey, and Malling (JACI 1998;102:558-562, PMID 9802362) endorsed calling allergen immunotherapy products 'allergen vaccines' or 'therapeutic vaccines for allergic diseases,' reflecting their mechanism of modifying immune responses rather than just suppressing symptoms. US clinical practice today prefers 'allergen immunotherapy' to avoid patient confusion with one-time infectious-disease vaccines.
Can I get an allergy vaccine at the pharmacy?
The four SLIT tablet brands (Grastek, Oralair, Ragwitek, Odactra) are prescription products dispensed by pharmacies. SCIT extracts are NOT available at pharmacies — they are prepared in the allergist's office.
Does Grastek work for all grass allergies?
Grastek contains only Timothy grass (Phleum pratense). Patients with cross-reactive grass IgE may derive benefit, but it is not a broad multi-grass product. Oralair covers 5 grass species, which provides broader grass coverage.
Is there an allergy vaccine for cat or mold allergies?
No FDA-approved SLIT tablet exists for cat dander, mold, dog dander, or tree pollen. Custom-mixed SCIT (no brand name) is the only standardized option for these allergens.
