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.
You can call 1-855-250-5111 to speak to a Gammagard Nurse Advocate who may be able to answer your questions. I just signed up for their patient help program called MyIgSource that promises to provide "answers and advocates."
I was told that a Registered Nurse will be calling me back today.
