It's rather about testing the vaccine on animals, eukaria. Philogenetically speaking, plants are our closer relatives than viruses and bacteria. How cruel of vegans to eat plants!I’d be comfortable with that as long as said sworn vegans are proscribed from any medical treatment that may harm viruses or bacteria in their bodies.Compulsory workplace vaccination rules cannot apply to vegans
"More than half a million vegans will be exempt if companies introduce compulsory vaccination rules in Britain because their beliefs are protected by employment law, legal experts have said."
Given that the emergence and growing threat of zoonoses is connected to intensive animal farming (and various environmental and wildlife abuses related to it), vegans shouldn't be expected to pay the price of meateaters' nonchalance. Next time you buy foise gras, think that you're risking the outbreak of the lethal H5N1 (fast mutating virus, so don't count on vaccines). ¡Buen provecho!
