From BBC News:
Experts at the BA Festival of Science, in Norwich, heard that vaccines could be created against the molecules which trigger allergies. The scientist leading the research – Dr Ronald van Ree, from Amsterdam University – said a vaccine with no side effects was in sight.
About one in 70 people have an allergy to foods such as peanuts or shellfish. New genetic engineering techniques are being tested to reduce the effect of the proteins in food that cause adverse – sometimes fatal – reactions. It is hoped that scientists will be able to make the molecules safe enough to use in drugs that fight food allergies via the immune system.
These would be used in conjunction with compounds designed to reduce inflammation – one of the most dangerous effects of allergic reactions.
