This statement from the article makes no sense, unless I am mis-understanding what is written:

"At birth, mothers transfer some of their antibodies against infection to their babies. But when babies are from 8 to 10 weeks old, the maternal antibodies have nearly run out and the babies typically have not started producing enough of their own."

It is my understanding that maternal antibody transfer across the placenta occurs in the last month of a full term pregnancy, and that the protection lasts close to one year for many antibodies.

Thoughts?
