"Newborns arrive into the world on the first day of life with brand-new immune systems that, like the children themselves, need to learn to cope with both helpful and harmful microbes in their environment," explained Galit Alter, co-senior author of the study published in Cell paper.

The study further explained the process by which the antibiotics transfers from the mother to the child. To study this mechanism the researchers used a tool called system serology. It examined the quantity and quality of antibodies against the pertussis in the blood samples of the mother and the umbilical cord which transfer blood, nutrients and immune factors from the placenta to the infant.

The research revealed that the placenta preferentially sifts out and delivers to the infant antibodies that activate natural killer (NK) cells, key elements of the innate immune system. The study further explained that several important immune cells are too immature to ensure effective protection in the newborns.
