There is a rising debate on whether annual canine vaccinations are necessary. While some veterinarians have suspected that immunity may last longer than was originally thought, there has not been enough research to back up these suspicions. Although vaccine manufacturers recommend annual vaccines, regulatory agencies don’t require data beyond a year other than for rabies vaccine. Reasons cited against annual vaccination include adverse side effects varying from itching to anaphylactic shock and possible development of autoimmune diseases.
For dog owners who are concerned that their animal companions may develop vaccine-related problems, there are annual titers that can be drawn to test your dog’s immunity to see if the vaccine is actually needed. If pet owners decide to skip years between vaccinations, they are urged not to skip the annual vet visit as wellness checks are still a vital part of keeping your best friend happy and healthy.
