Vegans who are concerned about vaccines should be encouraged to think about the wider picture. Not Spaghetti mentioned horeshoe crabs and there is certainly ongoing concern about the impact of medical research on species sustainability but this predates SARS CoV2.
It is true that the blood of the horseshoe crab has been used in the development of the Covid vaccine but also true that the peculiar qualities of its blood has played:
an unparalleled, integral part in ensuring environmental safety and that of nearly every drug and medical device in use today (van Holde and Miller, 1995; Loveland et al., 1996) including (e.g., clotting factors, insulin, and [other vaccines]; recombinant drugs; and implantable medical devices (e.g., heart valves and orthopedic devices) (Novitsky, 2009).

Recombinant technology or genetic engineering is a modern method used for the synthesis of therapeutic agents e.g. hormones, anti-rheumatic drugs, interferon and many others.
I understand the vegan ethos but I would also argue that it is a selective belief system:
Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals. Vegan Society
It is hard, arguably, impossible to live in the 21C without using products which contain some part of an animal. Animal tallows are used as cooling agents in our electrical devices and other products such as car tyres. Animal products are also used in everyday plastics as a slip agent. The alternative is plant based derivatives, usually palm oil, and we are all aware of the environmental damage including loss of vital animal habit inherent in the production of that. Three years ago, the plight of the orangutan and “dirty” palm oil production was a hot topic.
Three philosophical questions to pose to a vegan refusing the Covid vaccine:
1. Would he or she also refuse treatment for any other condition where the blood of the horseshoe crab has been vital in developing treatment?
2. Humans are also animals. The vaccine programme is as much about protecting others as it is about protecting ourselves. Is it cruel to refuse a vaccine which could prevent one person from infecting another with a potentially lethal virus?
3. How does he or she feel about using everyday products e.g. a mobile phone, a laptop or tablet, motor vehicles and everyday plastics which contain animal products and what lengths do they go to to select alternatives or eschew products altogether where there is no alternative.
