Exactly. Of course, the company that markets a potentially multi-billion dollar drug should not be trusted to comment on its safety.
That being said, I wouldn't let a single case of fatal pneumonia scare me away. Plenty of people on and off the drug will die of various maladies. That being said, I agree with cheerleader that it is a sign that doctors should consider closer monitoring of lymphocytes until they have more post-market experience with the drug.
It may be that a small percentage of patients on tecfidera have an idiosyncratic severe lymphocytopenic reaction putting them at significant increased risk of infections.
