2 ways of looking at this: 1) The main cause of infant death due to coronavirus seems to be complications from early labor and the baby being premature. Also related to hypertension in the mother. But it's only the leading cause due to lack of other causes, not necessarily because it's common. 2) Pregnant women also have a non-standard, somewhat suppressed immune system, since they're basically tolerating a (half-)foreign 9-month infection of sorts. It also explains, as you mention, being vulnerable to various types of infections. But if one of the causes of death for covid is cytokine storm, which is basically an over-responsive immune system failing to regulate itself, then it makes sense that pregnant women, with an over-regulated immune system, might have less risk from that aspect of the disease. More info on it if you look at theories on placental development and why women are more susceptible to autoimmune diseases. Pretty fascinating stuff.
