Why do some people get allergies, and others don’t?

Picture this: it’s a clear, bright morning in spring. You’re walking through the park with a friend, and the warm breeze floats delightfully over your skin, bringing with it the fragrant scent of local flowers in bloom, and the dewy smell of fresh grass. You smile, feeling a wave of contentment. “Don’t you love this time of year?” you ask your friend.He sneezes. “I hate it! It’s allergy season again!”Spring is a time that some people can enjoy the blooming life all around them, while others are a sneezing, stuffed up mess. Why is that? In this episode, we’ll try to answer this question. ​Du Toit G... LEAP Study Team. Randomized trial of peanut consumption in infants at risk for peanut allergy.
