So what could happen if Brownie Bun donated blood? Could it then be injected into someone who would… (Grimdark image ahead)
 

 
Uh, hmm… WHAT TO THINK?

I tried to donate blood once I got denied.

*always seems,
 
My autocorrect/auto complete seems to be acting up today…

So assuming the prior circumstances it would be possible to be injected by magical pony serum? Even if they don’t use it much anymore there almost always see, to be some sort of exception.

Pffffhahahaha! They’re so cute. X3c

Fun fact time! Horse blood has been medically important to humans in the past, starting in the late 1800s and saving thousands of lives.
 
Inoculating a horse with the toxin from a disease causing bacteria (diphtheria, and historically tetanus) causes them to produce antibodies, just as we would (it functions as a vaccinating agent). Since horses are so large, they produce a LOT of antibodies, and a lot of blood can be drawn at a time without injuring the horse. The blood would be separated into “horse serum,” which had no cells and a high concentration of antibodies. These antibodies bind to toxins and generally do a good job of nullifying them, and represent an immediate-action agent that can be injected once purified.
 
The down side, of course, is that equine antibodies are slightly different from human antibodies, and can cause (sometimes severe) allergic reactions. Most of the antibodies used for antitoxins and antivenoms are now fully human to avoid this (and usually produced by hybridomas, a white blood cell and cancer hybrid that is REALLY convenient and it’s amazing that they work at all). Better yet, we just vaccinate people directly for these diseases now.

Sudden panic at rejection of the blood?  
Nothing happens?

I suddenly worry and wonder what would happen if a vet used a… whatever unit of blood from a magic pony and put it in a normal one.

I’m sure there’s a horse somewhere that’ll need it.
 
I think.

Good man, donating blood.

I dunno what it is about this tumblr page but I find it cute and funny in a subtle way.

aw she cares so much.
