Allergy symptoms more at start of season

Recent studies have found that allergic people tend to have more symptoms at the beginning of the season. This is regardless of the medications taken. The following are the proposed explanations:
1) Sufferers get used to the symptoms and are therefore not bothered by them. So they did not report the symptoms.
2) Allergen-specific regulatory T cells may down regulate the inflammatory response after high exposure to the pollen at the beginning of the season.
3) Pollen at the later part of the season are less allergenic.
