Wellcome grants involving animal research 2019 to 2020
We support the use of animals in the research we fund if researchers can show that it is legally, ethically and scientifically justified.
This is our analysis of Wellcome grants involving animal research between October 2019 and September 2020.
The chart below shows the percentage of grants we’ve awarded over the past five years that have involved the use of animals.
22.1% of the grants we awarded from 2019 to 2020 involved animal research.
The data fluctuates each year because the applications we receive and fund vary each year. This means it's difficult to identify underlying drivers or clear patterns in the figures.
The increase in the percentage of applications involving animals is likely due in part to the closure of several funding schemes between 2018 and 2019. These included the Vacation Scholarships, Seed funding, Small Grants in Humanities and Social Science and the Public Engagement Fund. We would not expect applications for these schemes to include animals, so the overall percentage of grants involving animals would be lower while these schemes remained open.
Breakdown of animals by species
Mice are the most-used species in Wellcome-funded research, accounting for 62.6% from 2019 to 2020.
Zebrafish make up the next largest proportion (24.3%).
Other species include:
- fish (other)
- guinea pigs
- non-human primates
Non-human primates accounted for less than 0.1% of the animals used.
