=== Newborn's immunity and susceptibility to infections, vaccination ===
the immune system is relatively immature at birth and has to evolve during a life of exposure to multiple foreign challenges through childhood, via young and mature adulthood (including pregnancy), to the decline of old age. Besides frank infections and vaccinations, the newborn is exposed to other antigens. He or she comes from a relatively sterile environment ''in utero'' and is then rapidly exposed to multiple microbes [43]. The first major exposure to bacteria is during passage through the birth canal, and then as soon as he/she makes oral, skin and respiratory contact with the exterior. From then on, exposure to microorganisms is continuous. Many of the bacteria that colonize the gut and other mucosal sites are essential for healthy life, including digestion of food and acquisition of vital nutrients. They also impact on the development of the immune system <ref>Simon AK, Hollander GA, McMichael A. Evolution of the immune system in humans from infancy to old age. ''Proc Biol Sci''. 2015;282(1821):20143085. doi:10.1098/rspb.2014.3085</ref>
the newborn, and especially premature infants, have impaired neutrophil functions [4], putting the child at risk of bacterial infections. In preterm and newborn infants, classical monocytes and macrophages are also immature. Consequently, there is poor tissue repair, impaired phagocytosis of potential pathogens and poor secretion of bioactive molecules.
Overall, the innate immune system is muted at birth, a price probably paid by the fetus not only to tolerate non-shared maternal antigens but also to ignore the considerable amount of stress and remodelling that takes place during development. This makes the newborn, and particularly the premature baby, relatively susceptible to bacterial and viral infections.
