Gamagard I take every 3 weeks. It gives you IgG that B cells which are depleated produce. Ask for blood test . Got 2 bouts with pneumonia because of this. Discuss with your doctor. They do not include the specific test for antibodies so I encourage you to ask for and discuss with your provider! Good luck ! I was hospitalized 2 x with pneumonia. Almost died.

Stay away from people best you can , watch for fever and chills Your white count should not be down long .The wbc (nulasta) ex Rapidly raises it .Still need to be careful since the B cell are low which makes antibodies .When your wbc gets above 3 the risk of infection is much less

It will improve in time, but there is a treatment I took called IVIG. It is someone's antibodies, and helps boost your immune system. It's helped me.
