We're working to decrease and eventually end the use of animals in testing, research and teaching by promoting the development of innovative and effective alternative methods.

For the past few decades, The HSUS has conducted its campaigns promoting alternatives and the reduction of animal use in a way that avoids harassment of individual scientists. The organization has declined to participate in campaigns focused against individuals and feels strongly that violence, illegal action or the harassment and intimidation of animal researchers or any other category of people who use animals are unacceptable and cannot be condoned as society debates and moves away from the use of animals in research.

    Humane groups applaud removal of obsolete vaccine animal test requirements

    The European Pharmacopoeia Commission and the United States Department of Agriculture have recently revised 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. HSI and The HSUS welcome these developments, and call on vaccine manufactures to be pro-active in seizing these opportunities to end the use of animal testing on their products, and on other national vaccine authorities to follow these positive examples.
