Pet Vaccinations: A Brief Overview

Vaccination can protect pets, like people, from some diseases. A yearly vet appointment, as well as keeping your pet’s vaccines up to date, will help keep your cherished companion safe and healthy. You’ll find some basic information about your pet’s immunization requirements down below.


Vaccines are medical medications that stimulate protective immune responses in pets, preparing them to resist future illnesses caused by disease-causing substances. Vaccines can reduce the severity of future infections, and some can even prevent disease entirely. Veterinarians now have access to a wide range of vaccinations.

Is vaccination a guarantee of protection?

Vaccination is safe and successful for the majority of pets, preventing sickness in the future. Occasionally, a vaccinated pet may not develop appropriate immunity, and, while uncommon, these creatures may become ill. Although breaks in protection can occur, most correctly vaccinated pets never show indications of disease, making vaccination a crucial aspect of your pet’s preventive health care.

Which vaccinations should my pet get?

Discuss your pet’s lifestyle, access to other animals, and travel to different geographic places with your veterinarian, as these factors increase your pet’s risk of disease exposure. Not all pets should be immunized with all vaccines simply because they are available. 


“Core” immunizations are recommended for the majority of pets in a specific area. “Non-core” immunizations are only given to pets who have special needs. To personalize a vaccine program for your pet, your veterinarian will analyze your pet’s specifics, the diseases at hand, and the use of available vaccines.

When should my pet get a vaccine?

Most veterinary organizations, including the American Veterinary Medical Association and the American Animal Hospital Association, suggest that all dogs receive a set of “core” immunizations as puppies and subsequently at regular intervals as adults. Puppy shots are most commonly administered at 8, 12, and 16 weeks, one year later, and then every three years after that.


After dogs reach adulthood, there are differing viewpoints on how frequently they need vaccine boosters. Most dogs should be revaccinated every three years. However, your veterinarian may suggest otherwise based on factors such as your dog’s health, lifestyle, and vaccination history, as well as the vaccine manufacturer’s recommendations. If you have a rescue dog, you can also inquire about its recommendations with the organization or shelter.

Are vaccines for pets safe?

Yes. According to Bierbrier of the ASPCA, the possibility of an adverse reaction is rare. And the potential consequences of your pet contracting the sickness much outweigh the slight chance that your dog will suffer any major adverse effects.


Moderate adverse effects of immunization include discomfort or swelling at the injection site, light fever, decreased appetite, poor energy, sneeze, or mild coughing, according to the AVMA. Your pet may experience a “snotty nose” two to five days after receiving an intranasal vaccine, such as some forms of the canine flu or bordetella vaccine.


Numerous factors are considered when developing a vaccination plan for your pet. Your veterinarian will customize a vaccination program for your pet to ensure lifetime protection against infectious diseases. Your vet will assist you in determining which vaccines are necessary and which immunizations can be postponed or even skipped for your pet.
