Dear Professor Lederberg:

I have learned that you have recently complained about the impure state of
vaceines. I fully agree with your statement and enclose coptes of some of
our work with influenza virus vaccine. Bestdes of being an extremely impure
product, the efficiency of this vaccine has not been established beyond doubt.
Although the U.S. Publte Health Service confirmed my findings (Influenza
Survetllance Report No. 73: Influenza vaccine and ABO tnecompatibtility.
Communicable Disease Center. U. S. Dept. of Health, Education and Welfare,

> Public Health Service. IV, pp. 12-14, 1962), they harassed me a great deal. *
’ Furthermore, I was forced to publish most of the eltnically important aspects
ors petal
: ! of our work abroad.
ure
I enclose coptes of our work in this area and would not only apprectate your
comnents but would also be grateful to learn about your endeavors in this
dtrectton. .
Very sincerely yours,
Georg F. Springer, M.D.
