The United States has been called the OPEC of blood plasma because it exports hundreds of millions of dollars worth to other countries. Why does the US dominate the blood plasma industry? Because in the U.S. it’s legal to pay donors which increases supply. Some provinces in Canada have also allowed paid donors but 80% of the blood plasma given to Canadians is imported from the United States and, to make matters worse, some provinces have banned or are considering banning paid donation. A very good letter opposes the ban:

We are professional ethicists in the fields of medical ethics, business ethics, and/or normative ethics, and academic economists who study how incentives and other mechanisms affect individual behaviour. We all share the goal of improving social welfare. We have strong reservations regarding any Act or legislation (hereafter: “Acts”) that would prohibit compensation for blood plasma donations…….Both the ethical and the economic arguments against a compensatory model for blood plasma for further manufacture into PDMPs are weak. Moreover, significant ethical considerations speak in favour of the compensatory model, and therefore against the Acts.

The letter carefully discusses many of the objections such as that paid donations will drive out unpaid:

The compensatory model leaves open the possibility of donors’ opting out of compensation, or the operation of a parallel non-compensatory model. The United States does just this, and has an approximately 50% higher voluntary, unpaid, per capita blood donation rate than Canada. Germany, Austria, and the Czech Republic, where plasma donors can be compensated, likewise all have higher rates of voluntary, unpaid per capita blood donation than Canada.

Is paid blood plasma less safe?

Dr. Graham Sher, the CEO of Canadian Blood Services, has said, “It is categorically untrue to say, in 2015 or 2016, that plasma-protein products from paid donors are less safe or unsafe. They are not. They are as safe as the products that are manufactured from our unremunerated or unpaid donors.”

The letter is signed by two Nobel Prize winners in economics, Alvin Roth and Vernon Smith, by philosophers like Peter Jaworski, who did most of the heavy lifting, and by experts who have studied incentives and blood donation closely like Nicola Lacetera and Mario Macis. I am also a signatory.
