I would not worry about HIV from a rhogam shot. They screen blood products very carefully.
What you can worry about if you're looking for something...is the viruses we don't know about. there's no telling how many hepatitis viruses there truly are.
I hadn't read all the information here, but there were some stats in Ina May's book that convinced me the antenatal shot was worthwhile. My m/w uses Rophylac? or something that I always spell wrong that is cleaner as far as preservatives go. The effects of sensitization were just so devastating that the risk/benefit ratio for me personally worked its way out into me getting the shot. I didn't have MT's info though...but honestly I didn't read it more than once and I don't really understand it.
and what's done is done so I'm just going to go to bed instead.
I've had 3 doses of rhogam...one after my m/c and one during both pg's. And it was all for naught...both my girls are RH negative and oh goody, get to research this issue when they get old enough to have babies!
the one bizarre thing is that my m/w offered it to me after knowing dd2 was negative. She said some people feel like you can still sensitize, especially the more pg's you have. This made absolutely no sense to me, and it was weird because she's anti all the other vaxes. I didn't question her a lot on it because this is my last baby anyway, and it was 2 days post partum so I wasn't up for discussing stuff like that.
I had no idea it was a blood product the first time I had it either. Nice "informed consent", huh?
