Ubiq wrote”prophylaxis means before disease develops, ie before develop symptoms. could have pre or post exposure prophylaxis but not post symptom prophylaxis At that point it is a treatment not prophylaxis.”
I wrote “That is right, antibodies cannot be produced if the patient has never been exposed to the disease. So prophylaxis can be given and called what it is: prophylaxis. Post-exposure it MAY or MAY NOT be prophylaxis depending on whether the patient’s immune system was at all triggered. If it was triggered then the “prophylaxis” is not really “prophylaxis.”
