I'd be scary taking serum though. God knows what you could end up with, if you survive the bout with SARS.
Why do you say that. Serum/gamma globulin is both safe and effective, and, personally, have been amazed it was not used sooner, especailly once there were a fairly large number of patients who recovered from SARS.
There is also a risk, though small, that the serum from the donor could still contain viruses even though donors are screened for viruses like hepatitis,
