Re: Revising the Declaration of Helsinki
Surely we need to be more nuanced about the term 'vulnerable' - all of us may be 'vulnerable' to different things at different points in time. Poor pregnant women and sex-workers may be vulnerable in terms of their health or exploitation by others, but in no way compromised in their ability to choose whether to be in a research project or not, provided it is properly explained and there are no other coercive factors in play.
It would be patronising indeed to consider that their vulnerability in one area made them vulnerable in all aspects and removed their right to choose for themselves.
'Vulnerability' is a rather over-exploited term and is itself vulnerable to misuse.
