We're back with another edition of JMF Defined! Today we’ll be defining a type of Primary Immunodeficiency, Agammaglobulinemia.

Agammaglobulinemia is a Primary Immunodeficiency characterized by the absence of B cells, which produce antibodies to keep you healthy and strong. This means your immune system is more vulnerable, which leaves you more likely to get an infection. X-Linked Agammaglobulinemia (XLA) is the most common form.
