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.
I can't answer a single one of your questions, I just wanted to say welcome back and Holy Cow you are back at school already! You need a cape-Super CVID Girl!
Stay Healthy!
