Many of these beekeepers (25-60%) become sensitized to bee venom through the production of specific antibodies that target the bee venom. Although these antibodies are important in the triggering of an allergic reaction only a small number of sensitised beekeepers go on to have an allergic reaction with symptoms away from the site of the sting. These reactions can be severe and are known as anaphylactic reactions.\n\nThe study investigates why some beekeepers develop severe allergic symptoms after bee stings while others do not.\n\nThis study will explore factors in the blood that protect sensitised individuals from having anaphylactic reactions - meaning that despite being sensitised they are tolerant and do not react to subsequent stings.",[84],"Bee Sting",[86,87,88],"Immune tolerance","Anaphylaxis","Beekeepers","2025-04-29",{"date":91,"type":92},"2025-04-30","ACTUAL",{"date":94,"type":92},"2024-01-22",{"date":96,"type":80},"2027-10-01",{"name":5,"class":6},1]
