If you take the actions by Trump in context the US has very high drug prices largely because so many of the nedicines are produced abroad. He has a broader policy beyond covid treatments and vaccines to create a US production which the US Govt can price regulate and reduce dependance on overseas suppliers. The UK NHS has similar problems of paying huge prices for drugs. Thats why pharmaceutical is such a huge and profitable sector. As a businessman Trump understands how the sector works far better than any politician ....or journalist. Always best to ignore the liberal press like DW which is little better than the BBC. They only seek division and everything is reported through the prism of their political bias.From what I can see, all the newspapers are quoting the same "Welt am Sonntag" article. This does, indeed, state very clearly that Trump wants the vaccine for exclusive US use. ("Nach WELT AM SONNTAG-Informationen will sich die US-Regierung die Rechte daran exklusiv sichern ")
The article explains the complications involved in that CureVac is working in partnership with the Paul-Ehrlich-Institut, which belongs to the state and therefore the rights to use any research information could be withheld from CureVac.
However, CureVac is a private company, which will require "special measures" to stop any sale.
Politically difficult for the German government because stopping sales to Trump will generate yet another tantrum. Hence the bidding war, where the German government is regarding this as a business tactic which should stop any toys being thrown out of the pram.
One feels that the German government approaching a US firm for exclusive use of a vaccine which uses US research paid for by the US taxpayer would generate a somewhat different approach from the White House.
