Research overview: rabies vaccination and duration of immunity in cats

Rabies vaccination of cats protects both feline and human health given the lethal, zoonotic nature of the disease, and is legally required in many jurisdictions. Research on duration of immunity supported the development and licensing of three-year rabies vaccines for cats, as well as non-adjuvanted recombinant options developed partly in response to injection-site sarcoma concerns. This overview synthesizes the immunology and regulatory literature rather than one source, describing how duration-of-immunity studies underpin vaccination intervals, why rabies vaccination carries public-health weight beyond the individual cat, and how product choices balance efficacy, longevity, and safety. It matters because rabies vaccination is a cornerstone of both animal and human disease prevention, and evidence on immunity duration shapes the schedules that maintain protection.
