As a vaccine ingredient, "BSA" is something that people with alpha-Gal allergy might need to be aware of--
it's Bovine serum albumin. It's used in protein characterization and analysis (as a standard) and also in tissue culture (which is how it can become a possible ingredient in vaccines).
It's a protein component, though, not a glycosylation product, which means that it should be okay for most people. (Rather the way that refined oils "should" be okay for most people with seed storage protein allergy).
Another possible hazard present in some cell culture media is FCS-- fetal calf serum. It's basically the same kind of thing as BSA, but less refined and a greater mixture of protein components.
As I sit hear and re-read your post above, I get chills up my spine. I had a full blown reaction today after making myself a protein shake with Whey Protein, which has bovine serum in it. I had my 8 year old son call my wife at work, then 911. I gave myself two .15 shots of epinephrine, 1 shot of albuterol, and lay on the floor writhing. By the time EMS arrived it was already passing but they stayed with me probably 30 minutes until I felt a lot better.
