As I understand it, someone who is bitten by a rabid animal (and has not been previously vaccinated) should be given shots of:
2. and also started on a 'rabies vaccine', with several shots over a 3-4 weeks period.
If, however, we say the victim in unable to get/afford the 'rabies immunoglobulin' shot, but someone else was (a universal blood donar who hasn't been bitten), would it work for them to get the shot, then give blood to the victim? If the 'rabies immunoglobulin' shot gives the antibodies that fight rabies to the healthy person, and then via a blood transfusion, some of these antibodies were transfered to the victim, wouldn't that be the same as directly giving the victim the shot? But then I'm working off of high school biology only...
I feel like I should provide some explanation for your time and troubles, so I'll just add here that I'm doing some musing for a story plot.
Thanks in advance!
