evidence: Peanut allergies occur when the immune system mistakenly identifies peanuts as an allergen signalling immune cells to release chemicals resulting in adverse reactions that can range from mild hives, cramps, nausea and vomiting to life threatening anaphylactic reactions that require immediate medical attention. Severe allergic reactions can include impaired breathing, swelling in the throat, a sudden drop in blood pressure, dizziness, and even death. [...] The new peanut allergy vaccine is formulated by packaging bits of peanut proteins into the Sementis Copenhagen-vectored (SCV) virus platform. SCV is a ground-breaking technology developed by Dr Paul Howley, Chief Scientific Officer, Sementis and UniSA’s Professor John Hayball, Head of UniSA’s Experimental Therapeutics Laboratory. Prof Hayball says the peanut allergy vaccine tricks the immune system into seeing peanut allergens in a new light, so that the body responds normally instead of generating an allergic reaction.
