Immunotherapy can prevent recurrence of severe allergic reactions triggered by which exposure?

• A. Bee stings
• B. Wasp stings
• C. Peanut exposure
• D. Penicillin allergy

Answer: (B)

Venom immunotherapy is used to prevent severe allergic reactions to future insect stings by gradually exposing the immune system to the venom, building tolerance and reducing the risk of anaphylaxis if stung again. This approach has a well-established preventive effect for future stings, including wasp stings. Peanut exposure is addressed by peanut oral immunotherapy in research and practice, but it does not provide the same reliable protection against accidental anaphylaxis as venom immunotherapy. Penicillin desensitization exists for when penicillin is needed, but it’s a temporary tolerance during ongoing exposure, not a general, long-term prevention against all future penicillin reactions.
