"Carte Blanche is the alarming tale of how the right of Americans to say "no" to risky medical research is eroding at a time when we are racing to produce a vaccine and treatments for Covid-19.

Since then, the military has pressed ahead to impose nonconsensual testing of the blood substitute PolyHeme in civilian urbanities, quietly enrolling more than 20,000 non-consenting subjects since 2005. Most Americans think that their right to give or withhold consent is protected by law, but the passing in 1996 of modifications to the Code of Federal Regulations, such as statute CFR 21 50.24, now permit investigators to conduct research with trauma victims without their consent or event their knowledge.
