Summary

This study looks at how well venom immunotherapy protects people with Jack Jumper ant allergy years after treatment stops. About 100 adults who completed 3-6 years of therapy and have been off treatment for at least 18 months will have a supervised sting challenge and blood test. Researchers will also track field stings and quality of life to see if the protection lasts.
