Because the immune system is still developing, a newborn baby has not yet been exposed to pathogens in the environment. Given the overall high prevalence of pathogens in the environment, explain why more newborns do not die from these disease-causing agents
The pathogens stimulate a secondary immune response
Tand B cells were received across the placenta during gestation
Antibodies are received from their mothers mil
Babies are born with numerous developed, long-lasting antibodies, cells, and 1 cells
Additionally, newborns also receive some level of protection from diseases through passive immunity via antibodies passed on to them from their mothers during pregnancy. This provides some level of protection against certain pathogens until the baby's own immune system develops enough to produce its own antibodies.
Furthermore, newborns are also protected by the innate immune response, which is the body's first line of defense against pathogens. This includes physical barriers such as skin and mucous membranes, as well as immune cells that can recognize and attack pathogens.
Overall, while newborns are vulnerable to infections due to their developing immune systems, they do have some level of protection from both passive immunity and the innate immune response, which helps to prevent widespread mortality from disease-causing agents.
