Just wondering what peoples’ thoughts are on this. My blood type is O-negative and every time I get pregnant I had to get blood antigens injected into my thigh. They said it was to protect any future babies I may have from being attacked by my immune system. Is this RhoGAM injection important? Just was thinking if this product would have any of the same side effects or ingredients as vaccines? They told me what it was for and the dangers of not having it. Much like an explanation, they would give when explaining vaccinations. I just never thought about it in the same light as vaccines.
