VACCINE AGAINST CYTOMEGALOVIRUS

IT is still true that only a minority of cases of congenital mental defect can be ascribed to a specific cause, and of these only a small proportion are the result of infection in utero, but this group has received the greatest attention; for one thing, these cases are, in theory at least, preventible. Of this group, the cases which have so far received the lion's share of attention are, of course, those of rubella embryopathy. There are many reasons for this: they were the first to be recognized; rubella is a familiar and easily recognizable disease, to layman and professional alike; and, in addition to those cases of gross defect, there are a much larger number of children with relatively minor defects of hearing or vision due to this cause. However, there are two other agents of at least equal importance, namely cytomegalovirus and toxoplasma.
