Vaccine zaps allergy in record time

|

ALLERGY sufferers could bid farewell to their sneezes with a new generation of vaccines that take effect within weeks.

Existing vaccines for allergies involve three to five years of regular injections with increasing amounts of allergen - the substance that triggers an allergy. All the while the immune response slowly changes from a predominance of T-helper 2 (TH2) cells, immune cells responsible for triggering allergic reactions, to T-helper 1 (TH1) cells, which stimulate the production of protective antibodies.

Because nothing is directing allergens to the right place in immune cells, it takes a lot of allergen to generate a response.
