A mature nervous system (which controls your immune) system doesn't happen that early.This is manifestly not true (discussed below) but I did try to find a source for this assertion. I found several, all from site run by chiropractors, such as the one below:

Strengthening Your Immune System Naturally
There are many things that you can do naturally to help boost your immune system, that is not in the form of a shot.
The best thing you can do is to get regular chiropractic adjustments. Chiropractors focus on the nervous system, which controls every organ, muscle, tissue and cell in the body. When the vertebra in our spine misalign (subluxate), it puts pressure on the corresponding nerve(s). Whatever the nerve is controlling is thus affected. Since the nervous system controls the immune system, it makes sense to get adjusted once a month to make sure that your nervous system is working properly or even more often if you are feeling sick.No, the nervous system does not control the immune system.
A simple way of thinking about this is to consider persons with spinal cord injuries, especially high spinal cord injuries. Their nervous systems are impaired. Other than having a higher risk of infectious disease from the functional aspects of their disabilities, their immune systems are intact.

The Immune System and the Nervous System
Evidence is mounting that the immune system and the nervous system are linked in several ways. One well-known connection involves the adrenal glands. In response to stress messages from the brain, the adrenal glands release hormones into the blood. In addition to helping a person respond to emergencies by mobilizing the body’s energy reserves, these “stress hormones” can stifle the protective effects of antibodies and lymphocytes.
Another link between the immune system and the nervous system is that the hormones and other chemicals that convey messages among nerve cells also “speak” to cells of the immune system. Indeed, some immune cells are able to manufacture typical nerve cell products, and some lymphokines can transmit information to the nervous system. Moreover, the brain may send messages directly down nerve cells to the immune system. Networks of nerve fibers have been found connecting to the lymphoid organs.
The chiropractor's understanding of the relationship between the nervous system and the immune system is counter-factual.
