What is the difference between a one and three-year rabies vaccine?

There is no distinct difference between a one-year and two-year rabies vaccine besides the labeling. Dr. Ronald, a veterinary immunologist, says that annual rabies does have an additional benefit and are similar to the three-year vaccines on effectiveness and their immunity. However, one-year rabies vaccines should be administered annually.

You should note that the annual revaccination does not add nor improve immunity. Instead, the one-year immunization increases risks of severe reactions to the canine. Therefore, there are no medical or response differences in the two vaccine labels.

How do rabies vaccinations function?

To know how vaccines work, you first need to understand how a pet’s immune system functions. Once a strange disease-causing organism, such as bacteria or virus, gets into a dog’s body, its immune system forms antibodies to resist the agent.

When the pet’s body has developed antibodies, the particular disease strain won’t affect your pet again since the body will be in a position to recognize it and destroy it faster. Vaccinations are essential in young canines because some diseases are devastating and can come now and again.

A vaccine comprises tiny particles of a bacteria or virus that is changed not to cause an active ailment, but the antigen stays unchanged to boost the protective system. Once the vaccine gets to the body, the body will develop an immune reaction against the virus or bacteria.

If your dog is vaccinated against a disease, it’s antibodies will get into action in case of exposure.

How frequent does my dog need to be immunized?

Are three-year immunizations harmful to my dog?

There is no such big difference between the one-year and three-year Rabies vaccination because no additional disease agent nor volume administered can activate an immune response. Therefore, labeling is different for other immunizations.

Even though your dog takes a vaccine labeled for three years and is protected for those years, your dog is not safe before the law. Moreover, there is no danger in using a three-year vaccine despite the state’s laws requiring annual immunization.

How long does a rabies vaccine last?

A dog’s vaccination duration is protective dramatically depending on a state’s law because it is the law that determines how long a vaccine is effective. Some rabies vaccines are labeled as effective for one or three years, but their contents are no different.

Some countries rewire annual pet vaccination regardless of the duration the vaccine is considered protective. Your veterinarian will help you stay on plan with your dog as per your state’s law.
