ABSTRACT
Why vegans are hesitant about vaccines x First, vaccines typically have to be tested on non-human animals as part of official approval procedures. Since ethical vegans reject the notion that humans have the right to exploit non-human animals, they may reject vaccines at a philosophical level because testing still involves treating non-human animals as objects of use. [...]vaccines often, but not always, contain animal ingredients, including gelatin, lactose, and blood from endangered horseshoe crabs. [...]vegans are not one homogenous group. [...]while authenticity involves being true to oneself, it is also socially constructed and requires living up to particular norms or expectations of others. [...]being authentic involves both being oneself and fitting in.
