Animal testing in scientific research is projected to be phased out at an accelerated pace following the introduction of a new strategy aimed at fulfilling the government’s pledge. The plan, presented by science minister Lord Vallance, emphasizes the gradual elimination of tests as alternative methodologies become available, supported by a £75 million injection into research efforts.
Key milestones outlined in the plan include discontinuing regulatory animal testing by the end of 2026 for assessing potential skin and eye irritations from new treatments. By 2027, researchers are expected to halt mouse testing for botox efficacy and transition to DNA-based lab techniques for testing human medicines for adventitious agents. Additionally, by the conclusion of 2029, there will be a reduction in pharmacokinetic studies on dogs and non-human primates.
In conjunction with the strategy, funding of £15.9 million has been allocated by the Medical Research Council, Innovate UK, and the Wellcome Trust to advance innovative ‘human in vitro models’. This initiative includes the development of organ-on-a-chip systems to simulate drug effects on human organs, yielding more human-relevant results without animal testing. The focus will be on replicating human liver, brain, cancer, pain, and blood vessels in five UK-based research teams.
Lord Vallance expressed that the objective is to minimize animal testing wherever feasible and replace it with safer and more effective alternatives. While the announcement has been positively received by animal welfare groups, some are calling for legislative support to strengthen the government’s commitment.
Recent figures from the Home Office revealed a slight decrease in scientific procedures involving animals in 2024 compared to the previous year. Notably, procedures involving specially protected species like cats, dogs, horses, and non-human primates were reported. Lord Vallance affirmed that new licenses for controversial tests like the Forced Swim Test will no longer be granted, emphasizing the importance of phasing out such practices in favor of alternative methods.
Various stakeholders in the field, including the RSPCA and Animal Free Research UK, have welcomed the government’s strategic direction towards reducing animal experimentation in favor of more advanced and humane research methodologies. The push towards animal-free science is seen as a positive step forward, with calls for stronger legislative backing to ensure the successful transition to non-animal testing practices in the future.
