Kim,
Was just talking about this offline with someone. Request unvaccinated blood if you can. I know its a scary situation and feel for what you are going thru. If you need it to live not many other choices.
Sending you positive vibes Patriot.

I tried donating blood for my sister's upcoming hysterectomy. Docs said they need at least six to eight weeks to make this happen, maybe longer. This is a surgery that got moved up so didn't have that kind of time. Good news is docs way they do not think she will need a transfusion. Not sure which Kim you were talking to but praying for her. Saw a good article today that fasting triggered cell apoptosis is really big help along with the supplements many others have already posted.

Sounds like it's a bit too late to donate her own blood but for future reference you can donate your own blood if having surgery. Found this...
