It could be, but it comes from paid blood donors. It is a precious human resource regardless.
There are only a handful of countries which source their own immunoglobulin via unpaid blood donors and then create a /blood product/ (regulatory approved and marketed) for their citizens. Often, only people with specific diseases have the authorization and right to use this particular product and patients with other diseases have to use product imported that uses paid blood donors, which the public/private/national health insurance pays for likewise.
It's still a potential theory, but I really do think this Norwegian hematologist and his team know exactly what they are doing and are on the ball. Usually identifying antibodies for culprits of some previously unclassified disease is like trying to find a needle in a haystack. Sure, they had clues from the AstraZeneca vaccine, but this team is still extremely talented.
