i'm taking an immunology class and having a hard time finding out the answer to a homework question. i have scoured my textbook and the internet, and i'm not sure if my answer is correct. can anyone help me?
here's the question:
why wouldn't you use serum from someone with immunity to a bacterial infection to protect another from the same type of infection?
my answer is that serum contains antibodies and would be considered passive immunity. protection will typically only last a few weeks.
but, i'm not satisfied with that answer because it doesn't really explain why you wouldn't want to use it at all. i'm really stuck. thanks.
