Purdue just did a study on vaccinated vs unvaccinated Great Danes and found that even the ocassionaly-vaccianted had developed antibodies to the egg/chicken protein... most vaccines are grown on eggs. So not only do they have antibodies against the virus they were vaccinated against, but also the protein the virus was grown on... you feed that protein and the body mounts a rejection to it and then we wonder why so many allergies these days.
This very interesting information....Do you know a source for the study? I would love to forward this information to her...thank you
