This is not a good way to practice medicine. The vaccine insert warns us that vaccines are meant for healthy animals. Not for animals who are going to be anesthetized for a major surgery, such as a spay or neuter. Not for animals who have a chronic condition, like hypothyroidism, diabetes, allergies, or cancer. And not for animals with acute symptoms such as an ear infection or vomiting.
We don't often think about the timing of vaccines, and they seem to be given willy-nilly, as the opportunity presents itself. So I see puppies who have been given vaccine boosters every two weeks, or in an attempt to preserve the immune system, the rabies vaccine is given one whole week after the distemper vaccine. This is a really bad idea! Vaccines are immunosuppressive, and your pet's immune system needs time to recover from one vaccine before the next one is given.
When health problems arise after vaccines, typically drugs are given to suppress the symptoms, and the next booster is given because the vaccine schedule is paramount. This is also not good medicine. Health problems after vaccination indicate that the animal should not be vaccinated again, as the immune system struggles to detoxify itself. Instead the animal should be supported and stabilized with nutrition and homeopathic remedies, and then after recovery the idea of vaccination can be reconsidered.
it's your job as a pet owner and my job as a veterinarian to pay attention to my patients and not ignore their symptoms. Symptoms are the only way your body has to tell you that it is out of balance, and balance must be restored before it is disturbed again.
