28 歲的克裡斯·佈魯克斯史密斯曾經一度生活在恐懼之下，擔心哪怕吃下極少量的花生就會因過敏致死。在他報名參與一項預防過敏反應的新方法的試驗之後，他的生活終於發生瞭改變。
The method used, known as oral immunotherapy, has already been successful in children and babies with peanut allergies. But it wasn’t clear if adult allergies, which are more embedded, could be treated the same way.
這個試驗所使用的方法被稱為口服免疫療法，這種治療方法已經在對花生過敏的兒童和嬰幼兒中取得瞭成功。但研究者們尚不清楚的是，對於成年人更加根深蒂固的過敏癥來說同樣的療法是否有效。
At the start of the small trial, participants were given tiny doses of peanut powder mixed with food. And over many months, the quantities were gradually increased to whole nuts. All this happened under strict medical supervision.
在這個小規模試驗開始時，受試者被要求服下混在食物中的微量花生粉末。在接下來的數月中，花生粉末的量逐步增加到相當於整顆花生的含量。試驗過程始終在嚴格的醫學監督下進行。
By the end of the trial, the average dose tolerated had increased by one hundred-fold with patients able to eat out, socialise and travel without worry. This is early research, and larger trials are now needed to find out more about who could benefit from this approach in the long run.
到試驗結束時，受試者對花生的平均耐受劑量提升瞭 100 倍，並且可以在外出就餐、社交和旅行時不必再擔心出現過敏反應。這是早期的研究結果，而現在研究人員需要進行更大規模的研究來判斷哪些人能長期受益於這項治療方法。
