Say you survived a certain disease,
Your body has created a set of anti bodies that hell with that certain disease, now, if you donate blood, will said antibodies help a person who has never contracted said disease?
(sorry for the poor english)
In: Biology
sort of. Usually when you do a blood transfusion, the plasma (part of blood that contains antibodies) are separates from the red blood cells. So the packed red blood cells that gets transfused has very little usable antibodies.
If you’re transfusion plasma, then yes, you can acquire passive immunity, however, that passive immunity does not last forever. You may temporarily become immune to certain disease, but once those antibodies are gone, you are no longer immune. That said, during the freezing and thawing process of the plasma, most of the antibodies are destroyed.
