There was no incidence of RhD alloimmunization in either of the studies, as the sample size was insufficient for meaningful comparison of this uncommon outcome.
However, from two to three weeks post-administration, the concentrations were similar for both routes of administration. None of the women involved in the studies developed antibodies against the RhD antigen. The number of included studies and the number of participants are not enough to assess whether there are any differences. Some of these donors have produced Anti D because of a previous exposure e.
Others have volunteered to be given an intravenous dose of Rh D positive cells, so that they will produce Anti D. Luckily for our Rh Negative mothers, there are a small number of generous souls regularly donating their blood and thus keeping up a supply of Anti D Immunoglobulin in order to keep our babies healthy. These volunteers donate blood at regular intervals. Their plasma is screened for viral diseases and then pooled for the manufacture of Anti D.
In addition, the manufacturing process includes viral inactivation steps in order to further reduce the risk of viral transmission, before distribution. The anti-D immunoglobulin neutralises any RhD positive antigens that may have entered the mother's blood during pregnancy. If the antigens have been neutralised, the mother's blood won't produce antibodies. You'll be offered anti-D immunoglobulin if it's thought there's a risk that RhD antigens from your baby have entered your blood — for example, if you experience any bleeding, if you have an invasive procedure such as amniocentesis , or if you experience any abdominal injury.
Anti-D immunoglobulin is also administered routinely during the third trimester of your pregnancy if your blood type is RhD negative. This is because it's likely that small amounts of blood from your baby will pass into your blood during this time. This routine administration of anti-D immunoglobulin is called routine antenatal anti-D prophylaxis, or RAADP prophylaxis means a step taken to prevent something from happening.
There doesn't seem to be any difference in the effectiveness between the 1-dose or 2-dose treatments.
