Active immunization against diphtheria, scarlet fever, tetanus, pertussis, typhoid fever, smallpox and rabies was admirably dis cussed in 1946 in Edsall's (1) review covering 444 papers. Other aspects of active immunization are dealt with elsewhere in this publication. This chapter is therefore devoted to the function of cells in antibody formation, to immunization with the aid of ad juvants and to the inhibition of sensitization by feeding the an tigen.
Johann Freund (1947) studied this question.
