Hay Fever Cure

Registered nurse, Michelle is one of three million Australians who suffer allergic asthma, mainly in summer when the grasses are loaded with pollen. Just a little can set her off.

Australia is the fourth worst country for allergic hay fever and asthma - summer grasses are the major trigger. Over-the-counter drug prescriptions have doubled in the past few years, but they give temporary relief to only one out of three sufferers.

Dr Janet Davies has discovered our two types of summer grasses have different pollen allergens - people can be allergic to just one or both types. Temperate grasses like Rye are rife south. But Subtropical grasses, which used to be confined north, have now spread like wildfire. South, affecting more and more people. "What we are trying to do is to meet the needs of those people who are primarily allergic to those subtropical grasses. So I have now discovered all the allergen components of the Bahai and the Johnson grasses."

A treatment for sub-tropical grasses is crucial because with climate change, hay fever and asthma sufferers are likely to be in for much longer allergy seasons and higher pollen loads, spreading over more areas of Australia.

Dr Janet Davies says "We know vaccines work. Our immune system can tell the difference between a temperament and a sub-tropical grass. So if you're really allergic to a subtropical grass you need to be taking a treatment that's going to target the allergens within that grass.
