Serological evidence of immunity with coexisting sensitization in a type of human allergy (hay fever)

Abstract

Using ragweed h a y fever as an example of a type of allergy we record serological studies which were undertaken to explain the protection resulting from pollen injections. The results have indicated to us the production of an intfibiting or immune type of substance that prevented the allergen from reacting with the sensitized cell, and they have also demonstrated the coexistence of both sensitizing and immune antibodies in the specifically treated patients.
