Dear Herr Haagen,
Many thanks for your letter of 8 December. I regard it as unnecessary to make a renewed special request to the SS Main Office in addition to the request you have already made. I request that, in procuring persons for vaccination in your experiment, you requisition a corresponding number of persons for vaccination with the Copenhagen vaccine. This has the advantage, as also appeared in the Buchenwald experiments, that the testing of various vaccines simultaneously gives a clearer idea of their value than the testing of one vaccine alone.
With best wishes,
Heil Hitler!
Yours
