How do Pet Vaccinations Work?

If you visit the veterinarian on a regular basis, you have likely noticed your veterinarian recommending several vaccines or that you follow a vaccine schedule if you have a young pet.

Vaccinations are an important part of keeping your pet happy and healthy. Keep reading to learn more about vaccinations, what vaccinations are, why you should vaccinate if your vet recommends it, and more.

What’s a Vaccine? 

Vaccines are designed to trigger immune responses (your pet’s ‘protective’ system in their body) to prepare them for future contact (immunity). Vaccines promote the release of antibodies. 

Why Should I Vaccinate My Pet?

Preparing your pet for future contact is not the only reason to vaccinate your pet, though. You may also choose to vaccinate your pet for the following reasons:

  • To avoid paying for costly payments in the future to treat an illness 
  • To prevent disease from spreading from your pet to you (some illnesses can be passed– these are known as zoonotic illnesses)
  • Conditions, like rabies, will likely force you to put your pet down if unvaccinated when the bite occurred
  • Many apartment complexes, workplaces, rental homes, towns, and counties are now requiring your pet to remain up-to-date on vaccinations

Do Vaccines Always Work? 

In most cases, the vaccines do work. If your pet is experiencing another type of illness, like cancer, her immune system may not be able to handle the ‘fight.’ But, in a healthy pet, vaccines have been known to work properly in most cases. 

To ensure vaccines work as well as possible, you should follow the vaccination schedule your veterinarian recommends. 

How Does my Veterinarian Decide Which Vaccinations My Pet Receives?

Prior to your veterinarian developing a vaccination program, he or she will consider your pet’s lifestyle, any risks due to your pet’s lifestyle, and discuss any side effects (if any) of the recommended vaccinations.  

Always schedule regular visits with your vet to be sure that your pet is healthy and up to date on vaccinations.
