About American Anti-Vivisection Society
American Anti-vivisection Society Inc directs its giving toward animals rescued from laboratories, especially chimpanzees, monkeys, and other primates in sanctuary care. One of the clearest patterns in the recent record is support for sanctuary expansion: Project Chimps received $73,264 in 2024 and $70,150 in 2023 for BUILD IT! expansion costs to bring in more chimpanzees retiring from a private laboratory. The foundation also supports long-term care for primates with specialized needs. Oklahoma Primate Sanctuary received $50,000 in both 2024 and 2023 for monkeys from labs, including veterinary care, professional staff, and fresh diet. Its work extends beyond primates rescued from research to care for horses and foals rescued from premarin production. Recent grants also include support for chimpanzees retired from research at several sanctuaries, along with supplemental veterinary and medication funding. Across these grants, the foundation funds direct care, sanctuary capacity, and specialized health support rather than broad unrestricted initiatives. The grant record shows a consistent emphasis on animals with lifetime care needs, with many awards aimed at food, shelter, medical services, enrichment, and facility support.
What American Anti-Vivisection Society Funds
In sanctuary care, the foundation backed Chimpanzee Sanctuary Northwest with $42,500 in 2023 for chimpanzees formerly used in research and capacity building to accommodate chimpanzees left homeless by a facility closure, plus a veterinary care supplemental grant. It also gave $17,500 in 2023 and again in 2024 to Chimp Haven for care of more than 300 chimpanzee residents, each time with veterinary support. For primates beyond chimpanzees, Oklahoma Primate Sanctuary received $50,000 in both 2023 and 2024 for monkeys from labs, covering veterinary care, professional staff, and fresh diet. Born Free USA was awarded $17,500 in both 2023 and 2024 for general care of baboons and other monkeys, each time with a veterinary care supplemental grant. The foundation also supports rescued horses. Equine Advocates received $17,500 in 2024 for horses and now-grown foals rescued from premarin production, again paired with veterinary care support.

Most awards sit at a standard $17,500 level, with a smaller number of larger project or expansion grants.

The foundation is not described as making program-related investments and does not fund individuals. Several awards are supplemental restricted grants for veterinary care, medication, or wellness, alongside direct care and capital support.
