David Noah got his pneumococcal levels checked today at UCLA. He got the vaccine six weeks ago, and then they check his levels to see if he mounted a response.

Normally he mounts a response, even if it isn’t a great response, the problem is that he doesn’t maintain the antbibody level appropriately, so he has to be vaccinated more often than normal.

This is what signals the immune deficiency–you’re supposed to be able to hold on to an antibody level for a certain amount of time.

The problem is we don’t understand what’s causing it.
