Are we over-vaccinating our dogs and cats?

Over-vaccinating dogs and cats can lead to significant health concerns due to the potential for adverse reactions and immune system overload. Here’s an expanded look at common vaccines for both species:

For Dogs:

  • Rabies: Essential but can occasionally cause severe side effects like autoimmune diseases or neurological issues with over-vaccination.
  • Distemper, Adenovirus (Canine Hepatitis), Parvovirus (DAP or DA2PP): Core vaccines with risks of immune-mediated diseases upon overuse.
  • Leptospirosis: Prone to causing adverse reactions like lethargy or fever, with concerns about strain mismatch.
  • Bordetella (Kennel Cough): Repeated vaccinations can stress the immune system, potentially leading to allergies or chronic issues.
  • Lyme Disease: Can cause joint pain or immune-mediated diseases if overused.
  • Canine Influenza: Frequent doses might not provide additional protection but can stress the immune system.

For Cats:

  • Rabies: Similarly to dogs, over-vaccination can lead to rare but severe side effects, including vaccine-associated sarcomas (cancer at the injection site).
  • Feline Panleukopenia (FPV), Feline Calicivirus (FCV), Feline Herpesvirus (FHV-1): Known collectively as the FVRCP vaccine, overuse can lead to immune system fatigue or adverse reactions.
  • Feline Leukemia Virus (FeLV): Recommended for outdoor or multi-cat environments, but over-vaccination might not provide additional benefits and could lead to injection site reactions or other immune responses.
  • Feline Immunodeficiency Virus (FIV): This vaccine’s use is debated due to potential misdiagnosis of vaccinated cats as FIV-positive and possible side effects like lethargy or fever.
  • Chlamydia felis: Often included in FVRCP vaccines, frequent vaccination might not be necessary if the cat isn’t at high risk, potentially leading to unnecessary immune system stimulation.

Common Concerns for Both Species:

  • Immune System Overload: Continuous vaccination can lead to an overactive immune system, potentially causing autoimmune conditions or allergies.
  • Vaccine-Associated Sarcomas: Particularly in cats, but also in dogs, certain vaccines can lead to the development of sarcomas at injection sites.
  • Hypersensitivity: Both species can develop hypersensitivity to vaccine components, leading to allergic reactions or chronic health issues.
  • Titer Testing: As an alternative to regular booster shots, titer testing can assess an animal’s antibody levels, preventing unnecessary vaccinations and reducing the risk of adverse effects.

Given these risks, a tailored vaccination schedule, often based on lifestyle, exposure risks, and titer testing, is advisable. This approach helps in maintaining immunity while minimizing the potential for vaccine-induced health problems. Remember, the goal is to protect our pets without compromising their health through overuse of vaccines.
