Since the Rhogam shot is only given to pregnant mothers who have a negative blood type (and are therefore Rh-) I don't think it's widely known or researched. But, I'm very happy to share what I've learned and why I made the decision I did (which isn't for everyone). I'm working on the post now and will for sure post a link here when I'm done. Glad to have at least one person who I know will be interested in it!! :D
