Bovine Serum Albumin in Human Vaccines

This is not medical advice nor intended as medical advice.  

Absolute vegan exemptions from vaccines are limited in the 21st century to the UK alone, yet that may change. Many large national and international animal rights groups or vegan organizations have taken a "do not condone or condemn" approach for their followers. Many people understand that personal commitments to vegan beliefs can be very costly financially, legally, and may test the mind, body, and soul at new heights. Most USA states do not acknowledge vegan beliefs as a religious exemption, even if this general practice and flagrant disrespect is a form of psychological torture. And, at the international level vegetarian prisoners still do not have rights to vegetarian or vegan food as a human right.

Modern injections today, their single chemical ingredients, and their components are still mandated to be tested on animals. Essentially, nothing is cruelty-free about 21st-century vaccines. The main animal-based ingredient used by USA manufacturers is Federal Drug Administration FDA-approved Bovine Serum Albumin (BSA).  Obviously, this is not a vegan ingredient at all. And, there is concern over Bovine Spongiform Encephalopathy (BSE) that could evolve as a result of the ingredient. This is addressed at the FDA webpage:
