The key ingredient in Cetuximab is a particular carbohydrate that each one non-primate mammals carry of their cell partitions and tissues, Galactose-alpha-1,3-galactose, or, in case you’re pressed for time, alpha-gal.

Dogs have it, cats have it, and the mice cells concerned in the manufacturing of Cetuximab have alpha-gal.

If a tick then bites you, it trades some of your scrumptious blood for its saliva, which is a cocktail of nasty issues. An enzyme in that saliva tells your physique that there is a selection of harmful threats, and your immune system bans the whole lot in that saliva from coming into the physique, together with alpha-gal, which can be in each burger, steak, and bacon strip.

University of Virginia’s researchers have additionally linked the alpha-gal allergy symptoms with a better threat of coronary heart illness.

Scott Commins: This allergy appears as if it should typically go away over time, however the drawback has been that any further tick bites appear to trigger the allergy to return. And these are sometimes sufferers who wish to be outdoors.

Amy Pearl: I do know that my numbers have gone down, as a result of I’ve been retested a pair of occasions, however they’re nonetheless 10, 20 occasions what they need to be.

Dr. Commins continues to work in direction of an instantaneous treatment to mammalian meat allergy. In the meantime, the quantity of instances are rising.

Scott Commins: So what we have been making an attempt to do is figure on a vaccine associated to tick saliva, in hopes that we will forestall the allergic response from persevering with, or recurring, with further tick bites.
