evidence: Alpha-gal syndrome (AGS) is a condition where people develop an allergic reaction to products containing the sugar molecule alpha-gal (galactose-α-1,3-galactose). Alpha-gal is present in animal-derived products, including red meat, milk, and ingredients of animal origin in certain vaccines, like gelatin or bovine serum. However, mRNA COVID-19 vaccines don’t contain animal products, therefore they don’t carry the risk of causing allergic reactions in people with AGS nor would they be expected to cause a meat allergy.
