Plain-English summary
Recent discussions among veterinarians have focused on how often pets, like cats and dogs, should be vaccinated, especially since some worry about the side effects of yearly shots. Over the past ten years, veterinary groups have suggested that certain essential vaccines might not need to be given as frequently. Instead, they recommend that vaccinations be tailored to each pet's specific needs, weighing the benefits and risks. This review looks into how long vaccines protect pets and what factors, like age and exposure to diseases, can influence this protection. Overall, the findings suggest that while some vaccines may offer longer-lasting immunity, the best approach is to consider each pet's situation individually.
Abstract
Concerns about possible adverse effects from annual vaccination have prompted the reanalysis of vaccine protocols for cats and dogs. In the last decade, several veterinary advisory groups have published protocols that recommend extended revaccination intervals for certain 'core' vaccines. In addition, practicing veterinarians have been asked to consider vaccination as an individualized medical procedure, based on an analysis of risks and benefits for each vaccine in an individual animal. The calls for extended revaccination intervals prompted considerable debate in USA and internationally. Areas of concern include the amount of evidence to support prolonged immunity from various vaccines, the risk of poor responses in individual animals and the possible effects on population immunity. This review examines how the duration of immunity (DOI) to a vaccine is established in animals and humans. It reviews factors that can affect the DOI in an individual animal, including the types of immune defenses stimulated by the pathogen, and the vaccine, host factors such as age and the level of exposure to the pathogen. In addition, it examines DOI studies that were published for canine and feline core vaccines.
