Comment

Allergen of the Year is an annual "award" of dubious distinction voted upon by the American Contact Dermatitis Society. This is "designed to draw attention to allergens that are very common, under-recognized, merit more attention because they are causing significant allergic contact dermatitis or are no longer causing significant relevant disease (as in thimerosal)".
