Pneumonia Anyone?

Does anyone get Pneumonia constantly? I recently was referred to a immunologist due to recent bloodwork coming back bad for my immune system as I’ve had 2 different types of Pneumonia in the last month in a half that I was hospitalized for on separate occasions. The hospital staff knows me by now! Ugh! They don’t know if was my MS medicine that has been cause it as I was on Ocrevus so they took me off of that, which I’m not happy about as I loved that medication and they put me on Vumerity. Does anyone else get Pneumonia a lot due to our immune system?
