Please, do realize that if resistances were free, we would all be resistant already. We lived with those infections far longer than we did without. TANSTAAFL applies here as well, and even if the evolutionary pressure gets high enough to cause change (which will be far, far later than you'd like it to be, i.e. serious social trouble probably has a significantly lower threshold), it will be at a cost that is hard to predict, though likely it would be lowered resistances to something else, or maybe a higher risk of autoimmune diseases. Or something completely different.
