The immune system in the lungs is different and vulnerable in newborns

Newborns are more susceptible to infections, presumably because of their immature and inexperienced immune systems. The most common dangerous condition in newborns and infants are lower respiratory tract infections caused by viruses, especially respiratory syncytial virus (RSV). A study published in PLOS Pathogens shows how the immune system in the lungs during early life differs from the one in older children and adults.Ideally, newborns could be protected against RSV by vaccination, but it is known that the immune system in early life is less responsive to "conventional" vaccines.
