the American Animal Hospital Association (AAHA) Canine Vaccination Task Force reviewed recent research on vaccines and how long they remain effective. In 2011 they made recommendations based on this research.
This table summarizes their recommendations. To make it easier to read, I added a blue star under each core vaccine, and also spelled out some of the abbreviations used for the names and recommendations.
Core vaccines are recommended for all healthy dogs, while non-core vaccines are usually only given if your dog is in a high risk category. You should discuss the pros and cons of non-core vaccines with your vet before administering them.
Here is a short summary of the vaccines that your dog is getting:
Distemper - Core, immune response lasts for >5 years in healthy dogs,
dogs should be revaccinated every 3 years.
Hepatitis Parvo (adenovirus in the chart) - Core, immune response
lasts for >7 years in healthy dogs, dogs should be revaccinated every
3 years. There's an option for annual IN if your dog is at risk for
Corona - not recommended because (in 2011) not believed to be
Leptosspirosis - non core. Discuss with your vet.
Parainfluenza - non core. Discuss with your vet, intranasal may be
preferable if your dog tolerates it.
Rabies - Core. There are 1 year and 3 year vaccines available, follow the label on the vaccine your vet uses as to the revaccination interval. In addition, some municipalities do not allow 3 years between rabies vaccination and dogs/cats must be revaccinated annually, no matter which vaccine is used. Check your local laws.
