Common Variable Immunodeficiency Support Group
Common variable immunodeficiency (CVID) is a group of 20-30 primary immunodeficiencies (PIDs) which have a common set of symptoms but with different underlying causes. CVID's underlying causes are different, but the result of these are that the body doesn't produce sufficient antibodies in response to exposure to pathogens.
Also if you have CVID and your doc is dosing you every 12 weeks, if it were me, I would be finding a new doctor. IVIG is administered every 3-4 weeks. It only has a 3 week (approximately) half life. Meaning your body uses it up in that amount of time, sometimes quicker. There is NO LITERATURE supporting a 12 week dose for CVID. I'm worried for you on this dose ((hugs))
