Absolutely. A Canadian study several years ago showed a 1-2% sensitization rate when RhoGam was given only after delivery. Adding the shot between 28 and 32 weeks drops this to near zero. You just have to see one sensitized pregnancy and the amazing and heroic efforts necessary to save such a pregnancy (not to mention the emotional and financial toll on the family) to see the worth in an "extra" shot. Worth it's weight in gold? And there's no down side. If the baby's Rh negative, no harm.

Another can of worms and your point is well taken. I presume that a ptient won't lie to me about the paternity issue and so far, I haven't been disappointed (to my knowledge). Haven't had any sensitized babies yet. Thank G-d.
