1 October 2019 - Transparency has become a prominent topic in debates about health care, particularly when it comes to pharmaceutical policy.
There is a loud call for transparent prices, and indeed for more transparency in research and development costs, patents and clinical trials, and for declaring how much public funding has gone into medicines development.
The call for transparency sounds sensible, unquestionable and obvious. Shedding light promises clarity, good governance and better understanding and will hopefully improve things all-round. But as much as the light of the sun is good for our health it can also cause harm.
