Again, you are destroying your own argument.

1. Lifelong immunity to pathogens is possible with naturally acquired immunity.
2. If the pathogens are mutating so fast the immune system cannot keep up, why isn't everyone sick?
3. How can herd immunity work as you suggest if the pathogens are mutating so fast. Surely the vaccines would be rendered ineffective by the same process. (There are many reasons that vaccines do not have the efficacy they are claimed to.)

If not going to insult you as you have tried to insult me, I'll let logic speak for itself.
