Each year, more than 100 million animals—more than three each second—are bred, injected, infected, cut open, genetically altered, and more, in the name of science.
Biomedical research aims to discover the causes of human illnesses and to prevent or treat them, but the benefits of today’s health research are becoming harder to see. A stunning 9 out of every 10 candidate new medicines that appear safe and effective in "animal models" fail in human trials due to unforeseen toxicity or lack of effectiveness. Research that never delivers because of irrelevant or misleading animal models delays medical progress and risks the safety of volunteers in clinical trials.
HSI’s Science Team is exposing failed animal models and pressing for funding to be shifted to more promising—and ethical—avenues of research.

New poll shows Koreans overwhelmingly support policy changes and increased funding to replace animal testing
A new nationwide public opinion poll reveals that 85 percent of Koreans support increasing research funding for alternatives to replace animal testing. The vast majority (also 85 percent) of those polled would prefer that their tax dollars be spent on non-animal test methods instead of animal testing. The poll was commissioned by Humane Society International and conducted by Realmeter.

Humane Society International and The HSUS applaud removal of obsolete vaccine animal test requirements
HSI applauded the European Pharmacopoeia Commission and the United States Department of Agriculture for revising their requirements for the safety assessment of vaccines to remove or waive two controversial and scientifically unnecessary animal tests, a move that could spare scores of animals going forward.
