Which therapy is indicated to reduce sensitivity to future bee stings in allergic individuals?

• A. Antibiotics
• B. Venom immunotherapy
• C. Epinephrine injections
• D. Antihistamines

Answer: (B)

Venom immunotherapy desensitizes the immune system to bee venom, reducing the risk of a systemic reaction to future stings. It works by exposing the person to gradually increasing amounts of bee venom in a controlled setting, which shifts the immune response away from an IgE-driven allergy toward tolerance. Over time this induces IgG4 blocking antibodies and regulatory T cell activity, so when a real sting occurs, mast cells and basophils are less likely to release mediators that cause a severe reaction.

This approach is specifically used for individuals with a history of systemic (life-threatening) reactions to bee stings or for those at high risk of frequent exposure who want durable protection. It requires a monitored treatment course with buildup and maintenance phases because reactions can occur during the injections themselves.

Antibiotics tackle infections, not allergic sensitivity to venom. Epinephrine injections treat acute anaphylaxis when a sting occurs but do not prevent future reactions. Antihistamines help mild symptoms but do not modify the underlying allergy. Therefore venom immunotherapy is the option that reduces sensitivity to future bee stings.
