Wellcome grants involving animal research 2021 to 2022
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 2021 and September 2022.
The chart below shows the percentage of grants we’ve awarded over the past five years that have involved the use of animals.
23.2% of the grants we awarded from 2021 to 2022 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.
Breakdown of animals by species
Zebrafish were the most-used species in Wellcome-funded research, accounting for 49.9% from 2021 to 2022.
Mice make up the next largest proportion (47%).
Other species include:
Non-human primates accounted for less than 0.1% of the animals used.
