Lush Prize 2022 winners:
the New Zealand Anti-Vivisection Society

What does putting a mouse into a jar of water tell us about human mental health?

Campaigners in New Zealand who asked this question were today awarded a £50,000 prize for best global project to persuade a regulator to prevent animal testing.

The Forced Swim Test is a ‘scientific procedure’ that involves forcing small animals such as rats or mice to swim in an inescapable beaker of water until they ‘give up’ and float. The theory was that a depressed rodent would give up more quickly than a happy one.  Since the procedure was invented in 1970, mice in their thousands have been given anti-depressants and even genetically modified to induce depression, before being dunked.

Researchers, perhaps unsurprisingly, are becoming increasingly sceptical about whether this ‘test’ has any value at all. An analysis conducted with data from four major pharmaceutical companies found that the Forced Swim Test was less predictive than chance at determining if a compound would be an effective antidepressant for humans.

Judges at the Lush Prize were impressed by the way the New Zealand Anti-Vivisection Society had focussed in on one quite obviously questionable test to tell a more general story about the wider issues of trying to use different species to tell us about how chemicals affect humans.

The Society’s work led New Zealand’s Economic Development, Science and Innovation Select Committee (20th February 2020) to conclude that the test was ‘largely useless’. Subsequently the ‘animal ethics committees’ there have begun declining applications to run the test.

Rob Harrison, Lush Prize Director explained:

“The Prize was set up ten years ago to help bring about an end to all testing on animals, not least because they consistently give misleading results on solutions to human health problems.  The work of the New Zealand Anti-Vivisection Society showed us that one way to get to this goal could be to persuade governments to reject one test at a time.  They also did great work persuading students and others to sign petitions and draw public attention to the campaign.”

The Prize categories: – 

  • Public Awareness: public awareness-raising of on going testing
  • Science: for the development of replacement non-animal tests
  • Training: training researchers in non-animal tests
  • Lobbying: policy interventions to promote the use of replacements
  • Young Researcher: to researchers under 35 years old specialising in animal replacement research
