New Vaccine Wards Off Allergy for Longer with Fewer Shots
June 1, 2003
A new allergy vaccine reduces the number of injections a patient needs to receive. The vaccine attaches a molecule to allergens found in ragweed, a plant that triggers hay fever symptoms. The molecule disguises the allergens so the immune system doesn't react to them. Patients receive six weeks of shots instead of the common year-round treatment. Early test results have shown that patients have had relief during more than one hay fever season.
