It has never been more important for us to talk about the definition of veganism in the context of medications, including vaccines. The definition of veganism recognises that it is not always possible or practicable for vegans to avoid participating in animal use, which is particularly relevant to medical situations. In the case of Covid-19, vaccination is playing a fundamental role in tackling the pandemic and saving lives. As there is currently a legal requirement that all vaccines are tested on animals, at this point in time it is impossible to have a vaccine that has been created without animal use.
