Yes. Vegans will not get flu jabs if eggs have been used to create them.

Proponents of the animal rights movement, such as PETA, stand against the use of animals for research under any circumstances. Ingrid Newkirk, the founder of PETA, has been quoted as saying "Even if animal research produced a cure for AIDS, we'd be against it." Animal welfare groups, by contrast, believe that animals can and should be used in research to further the treatment, cure and prevention of human disease.
Animal rights activists also oppose the use of animals for producing food or clothing. Even the use of eggs for food is opposed by some animal rights groups. Conversely, animal welfare advocates endorse the use of animals for food or clothing but seek methods to ensure that animals used for these purposes have their basic needs met and are handled in a humane fashion.
Animal rights groups would prohibit the breeding and exhibition of animals in zoos and other facilities, even when these species are endangered or extinct in the wild. These same groups believe that dogs used in search and rescue operations are being exploited by their human handlers and should be prohibited from being used in such a fashion, regardless of the fact that these dogs may be responsible for saving human life.
In summary, the philosophies of animal rights proponents and animal welfare advocates are extremely different. There are many people who believe strongly in the animal welfare cause who simply cannot support the cause of animal rights. Conversely, many animal rights advocates believe that animal welfare groups simply do not go far enough in protecting animals and securing their rights. Wherever an individual stands in regards to animal rights versus animal welfare, it is worth noting that these causes are not synonymous of one another.
