The Harvard Medical School has announced it is closing its primate research center, stating financial reasons due to funding uncertainty as behind their decision, which would send about 2,000 monkeys to other U.S. facilities.

Since about 2010, four monkeys at the New England Primate Research Center in Southborough, Mass., have died, and the Department of Agriculture has cited the center for failing to comply with the Animal Welfare Act, according to the New York Times.

The center is credited with various AIDS achievements, including finding the first clear evidence that AIDS is caused by a virus and demonstrating a vaccine is possible.
