One reason why contagious vaccines are controversial is that we can’t guarantee that the viruses used to spread these vaccines can’t mutate and jump species. To create contagious vaccines, scientists take antigens (proteins that trigger an immune response) from a microbe and splice them into viruses that naturally infect only one type of animal.
