What are the opposite words for Passive Cutaneous Anaphylaxis?

Passive Cutaneous Anaphylaxis (PCA) refers to an allergic reaction that occurs when an individual is exposed to a specific antigen, leading to the release of histamines and other chemical mediators. In terms of antonyms, the opposite of PCA would be an absence of an allergic response. This could be due to a lack of exposure to the antigen, a strong immune system that does not react to the antigen, or being desensitized to the antigen through immunotherapy. Another possible antonym for PCA could be an active immune response, whereby the immune system recognizes and attacks foreign substances without triggering an allergic reaction.
