( Hay fever, food and skin allergy )
Allergies
Allergy research ranges from a few weeks of nasal spray in pollen season to longer studies that try to retrain the immune system. Choose this area if allergies affect you or your family.

What studies here look at
Seasonal allergy studies often run during spring or fall, testing sprays, tablets or under-the-tongue drops against symptoms you record each day. Some take place in a room where pollen is released in measured amounts.
Food allergy research includes studies that build tolerance with tiny, steadily increasing doses of the food, always under close supervision. Other studies look at hives, eczema linked to allergy, and allergic asthma.
Who studies often ask for
Every study writes its own requirements, so read this as a picture of who tends to be asked, not a checklist.
- Adults with hay fever or year-round allergies
- People with a diagnosed food allergy, such as peanut or tree nuts
- People with chronic hives
- Parents of children with allergies, for studies that include children
