evidence: 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. [...] However, the Vegan Society encourages vegans to look after their health and that of others in order to continue to be effective advocates for veganism and other animals. It is the responsibility of each individual to make an informed decision about vaccines, bearing in mind the definition of veganism, with support from their local healthcare team. Our friends at the Vegetarian Society have summarised the government and manufacturer information on the Covid -19 vaccination into some key points.
