This is still based on a cause/effect relationship. The immune system isn’t learning and planning in the sense that sentient organisms with a nervous system do.
But if u argue that this is purpose u basically have to say the immune system is conscious (which im actually not opposed to). Its not conscious in the exact same way as a nervous system but it is conscious. This can be extended then to basically anything that is able to respond to an ever changing environment (Check out The Web of Life by Fritjov Capra) he has an interesting take on this idea
Anyway regardless of the semantics game we are playing with purpose i just wanted to clear up the misconception that some ppl have with how evolution occurs

The immune system is actually part of the nervous system to the extent that the thoughts you think can and do affect your lower brain centers and which in turn effect your immune systems actions. The formal study of this is called psychoneuroimmunology.
All these interacting systems have the sole purpose to maintain stasis and ultimately survival.
I think part of our disagreement is your use of the term “purpose”. You appear to be using it in some other manner that it’s true meaning:
- the reason for which something exists or is done, made, used, etc.
- an intended or desired result; end; aim; goal.
- determination; resoluteness.
- the subject in hand; the point at issue.
- practical result, effect, or advantage: to act to good purpose.
- to set as an aim, intention, or goal for oneself.
- to intend; design.
- to resolve (to do something): He purposed to change his way of life radically.
- to have a purpose.
