Hi. My daughter age 15 does weekly voluntary work at a vet and at a wildlife sanctuary. A year or two ago she started with a rabies vaccination course. She did not finish it and fell ill. Were not sure if she is allergic to the vaccination. Is trying again dangerous? She has put in thousands of hours at the vet because of her passion. She wants to become a vet. Note: She took the vaccine for preventative reasons. What are your thoughts on this. Should she try again?
