Ethics of biomedical research Flashcards
where are animals used?
Universities & med schools- 49.2% of total UK procedures
Commercial organisations- 25.3%
Charities- 13.2%
Government- NHS- Public bodies, public health labs- 12.3%
Why are animals tested on?
Creation & breeding of genetically modified animals (mainly mice)- 48.6%
Basic research (how it works)
Regulatory testing
Research that translates animal to human- 8.6%
Protection of natural environment e.g. making animals less likely to damage their environment by genetically altering them
Preservation of animal species e.g. testing pesticides for effect on animals- <0.1%
What species are commonly used?
Mice- 60% Fish-17% Rats- 9% Birds Others Specially protected species- its, dogs, horses, primates- 1%
Moral question- moral value of animals vs value of research + moral values of humans & human wellbeing’s
Does potential benefit to humans justify causing harm & suffering to animals
Is the use of animals in research still necessary?
No:
- Human costs of experimenting on animals is regarded as irrelevant- so why are studies being done in first place?
- Many animal studies are poorly designed
- 92% of drugs shown safe & effective on animals fail in human trails- animals have suffered & no benefit for humans has come out at end
Yes:
- Argue that potential benefit for human justifies harm of animals
- In-vitro or in-silico investigations cannot replicate the function of complex living systems
- Less morally acceptable to experiment on humans
Why not test on humans?
Paying research subjects risks selecting for the most needy, most vulnerable groups- economic coercion
Many regard people as having more moral worth than animals
But should animals suffer in pain for human knowledge, however altruistic the aim is?
Rule for testing on animals- animal welfare ethical review boards?
Principle of replacement, reduction & refinement
Ensure that, whenever possible, a scientifically satisfactory method or testing strategy, not entailing the use of live animals, shall be used instead of a procedure
Ensure that number of animals used in projects is reduced to a minimum w/out compromising the objectives of project.
Ensure refinement of breeding, accommodation & care & of methods used in produces, reducing any possible pain, suffering, distress, or lasting harm to animals.
What does Jeremy Bentham argue?
argues that humans based on their ‘special characteristics’ are not as special as they seem & if we think main point of moral consideration is ability to feel pain, then animals are as worthy of moral consideration as humans
Animal testing- some moral questions
Is no consent different from dissent in this case?
Deontology- never use someone as a means to an end
Is a non-human animal someone?
If it is wrong to kill an animal or to cause it to suffer to further human ends through research, what about food?
- We kill more animals for food than for research
If there are enough similarities for experiments on animals to be useful- why not for moral consideration & rights talk?
Testing on humans- what was the Tuskegee syphilis experiment?
1932-1972; united states
399 African American men w/ untreated syphilis monitored for 40 years
Told only that they would be getting free medical care
Not told of their diagnosis- given placebos rather than treatment
What is the HeLa cell line?
African-American women’s cancer cells grown in culture
An immortal human cell line- still replicating
Consent from her or her family never sought
Total mass of HeLa cells > 50 million tones
Still in use today
Raises questions:
- Would her material have been treated this way is she was white?
- Who owns your genetic material?
- Since HeLa cells have mutated, does this justify their continued use?
- Do the undoubted breakthrough that the cell line has generated retrospectively justify the way they were acquired?
Nazi experiments?
Nazis claimed not to see some people as fully human
But that didn’t mean they didn’t their potential for medical research
Denial of humanity
Indifference to suffering
Some experimental results still in use- knowledge used as bases of some medical knowledge today
Testing covid vaccine in Africa?
Economic coercion?
Nit all countries have strict code
What is the Nuremberg code?
Ethical guideline of ensure that medics never again participate in atrocities
Forerunner of the four pillars approach
Enshrines (fire rule) voluntary consent of subject
Not officially adopted in any jurisdiction
What are the 5 rules of ethical human research?
- Obtain consent
- Minimize risk of harm to participants
- Protect anonymity & confidentiality
- Be transparent to subjects
- Respect participants right to w/draw.
None of these translates to non-human subjects
