evidence: In a video from August 2023, conspiracy theorist Alex Jones and InfoWars employee Rob Dew claimed that the Moderna and Pfizer-BioNTech COVID-19 vaccines contain a bovine protein called alpha-gal that "creates an autoimmune response in those that take the shot so that many of them can no longer eat beef". [...] However, the Moderna and Pfizer-BioNTech COVID-19 vaccines don’t contain any ingredients of animal origin. Since the alpha-gal present in some vaccines comes from animal products, the mRNA COVID-19 vaccines also don’t contain alpha-gal and therefore wouldn’t be able to cause an allergic reaction in people with AGS.
