Q. Professor, please describe these vaccinations briefly to the Tribunal.

A. First, a group of 40 persons was vaccinated. The first vaccination was done with one cc. intramuscularly. One was a vaccine made of murine typhus virus vaccine. In no case did local reactions of temperature or other symptoms occur. The second vaccination took place a week later. This was again one cc. of vaccine introduced intramuscularly. This was no longer pathogenic to human beings. To complete the story I have to say that between the Schirmeck vaccinations in May and these vaccinations, I had turned to the production of a louse typhus vaccine; this vaccine contained live virus. Before it was used in Natzweiler as a vaccine, we tested it on ourselves, that is, with some collaborators, to ascertain the tolerability and effects. We were roughly ten persons, members of the institute and also students. Only then did we use the vaccine on the prisoners in Natzweiler. Four weeks after the last vaccination there were the usual serological examinations. The Weil-Felix reaction was used. The average titer value, let me say, was better than in the vaccinations with the rat virus. It was, namely 2,000. I need not go into these details. The general reactions were normal reactions to inoculation, temperature, and headaches; but there were no manifestations of actual typhus as a result of inoculations.

Q. You are speaking of a first group, so I assume there must have been a second group. How did you carry out the vaccination of the second group?

A. It occurred to me that instead of injecting the vaccine, the vaccination could be performed by scarifying the skin in the same way as you scrape the skin to make a smallpox vaccination. Therefore, as with the first group, with the same living virus vaccine, I vaccinated 40 additional persons with scarification of the skin. Let me point out that the experiments on myself and on my assistants were carried out in the same way, with scarification of the skin. The reactions were comparatively mild, corresponding roughly to the reactions to vascular typhus vaccine, so that we had no misgivings about undertaking this kind of vaccination.

Q. You described the reactions of yourself and the volunteers as very slight. Now, the reactions of the prisoners were stronger, were they not?

A. Yes. They were stronger again. And this we can only explain by believing that the general state of health among the prisoners was lower than among my associates; but there was no such thing as a natural manifestation of typhus or any fatalities.


Q. But, Professor, to this statement I shall have to put to you something which was said before this Tribunal and which is quite different from what you have just said. I am referring to the testimony of the witness, Edith Schmidt. On 9 January 1947 (Tr. p. 1371), she said that you had carried out vaccination experiments on 100 to 150 persons in Natzweiler, and out of these experiments roughly 50 are said to have died from the control group. Fraeulein Schmidt stated that she knew this from notes which your technical assistant, Miss Crodel, had made about the typhus experiments at Natzweiler. Can you please tell the Tribunal to which notes Fraeulein Schmidt was referring—in other words, how do you explain her testimony?

A. It is utterly impossible for Fraeulein Schmidt to have seen records of notes of my vaccinations in Natzweiler in which fatalities occurred because as I have already said no one died following the vaccinations. These notes of Fraeulein Crodel’s which Fraeulein Schmidt saw do not refer to the vaccinations. That can be seen from the numbers mentioned, by Fraeulein Schmidt, because I only vaccinated 80 persons at Natzweiler, not 150 to 200 as the witness stated. The witness apparently took this number and the concept of a control group from later writings, which are to be discussed hereafter; but I can imagine to which note she could have been referring.

Q. Please continue, Witness.
