In groundbreaking research, a team of scientists from Sechenov University (Russia) and Vienna Medical University (Austria) have unveiled the world's first recombinant vaccine for addressing cat allergies. This pioneering innovation displays an efficacy rate of 85% and has the potential to significantly reduce treatment periods when compared to traditional methods. The incredible findings were published in the revered journal Allergy. Human clinical trials lie ahead, determining the vaccine's future impact.
Approximately 25% of people globally combat cat allergies, with symptoms ranging from nasal congestion, skin rashes to asthma. These reactions are initiated by proteins Fel d1, Fel d4, and Fel d7 found within cat saliva and fur. Conventional therapy, allergen-specific immunotherapy (AIT), requires numerous injections of allergen extracts, which may cause side effects and may not tackle all protein variants.
"Conventional medications are tough to dose, and their effectiveness is limited," says Alexander Karaurov, the study's lead researcher.

Utilizing biological insights, scientists identified essential fragments of allergenic proteins (peptides) that induce reactions. These fragments were then bound to the PreS protein, a compound that amplifies the immune response and decreases the risk of complications. With genetic engineering, five vaccine forms were devised, two of which demonstrated exceptional outcomes.
Experiments on rabbits confirmed that upon receiving two vaccinations, the new vaccine suppresses up to 85% of allergic reactions, surpassing existing treatments. It's worth noting that traditional treatment protocols necessitate 6 to 15 injections. Notably, the vaccine's antibodies also provide moderate protection against dog (Can f1) and horse (Equ c1) allergens, suggesting possible broader applications.
The researchers are now preparing for human trials. If the trials prove successful, millions of allergy sufferers could gain a safe and swift solution, enjoying interactions with pets without fearing for their health. The project is supported by a Russian Science Foundation grant "Allergochip RF" (No23-75-30016).

How the Recombinant Vaccine Works
- Targeted Immune Modulation: PreS-Cat triggers the creation of antibodies that block basophil activation, reducing allergic inflammation.
- Increased IL-10 Production: IL-10, an anti-inflammatory cytokine, helps regulate immune responses, leading to reduced allergy symptoms.
- Hypoallergenic Design: The vaccine's hypoallergenic design lowers the risk of adverse allergic reactions associated with whole allergen extracts.
Benefits Compared to Traditional Methods
Traditional cat allergy treatments usually consist of avoidance, symptomatic treatment with antihistamines or corticosteroids, or allergen immunotherapy using cat allergen extracts:
- Safety: The recombinant vaccine's hypoallergenic design reduces the risk of adverse allergic reactions due to the use of whole allergen extracts in conventional methods.
- Efficacy: By specifically stimulating immune tolerance mechanisms like IL-10 production and preventing basophil activation, the recombinant vaccine offers profound and targeted immunomodulation.
- Convenience and Compliance: Recombinant vaccines can be engineered for more controlled dosing and potentially reduce treatment duration or frequency.
- Novel Immune Pathways: The vaccine targets protective IgG antibodies that effectively block allergen interaction with IgE on effector cells, a mechanism that traditional methods may trigger poorly[4].
The development of such recombinant vaccines signifies a crucial advance because they aim to re-educate the immune system more precisely and safely, addressing the root cause of allergies rather than solely managing symptoms.
In summary, the revolutionary cat allergy vaccine employs hypoallergenic, targeted immune modulation to inhibit allergic pathways more effectively and safely than traditional allergen immunotherapy, offering improved patient outcomes and potentially better compliance[1][2][4].
