When they're first born, a human infant actually has a full immune system, but most of this system's immunity was supplied by the mother during its time in the womb. After six months, the immune system has produced its own cells for protection, and is mostly its own.
Yes - innate immunity is found in all mammals.
mostly antiviral immunity is the result of cell mediated immunity and antibacterial immunity is result of humoral immunity
Natural Passive Immunity
Passive natural immunity
Passive immunity is different from active immunity because it means that you can get it from another person and you can give it someone else. Active immunity is when you get it by yourself, not from another person, and you cannot pass it to another person.
You are born with innate immunity which consists of natural barriers to infection. Acquired is developed after birth when you come into contact with antigens

Because they have either respectively not yet developed sufficient immunity, or may have weakened immunity.
hearing is the most developed sense at birth;vision is the least
Natural active immunity to chickenpox is developed by being infected with chickenpox disease.
Yes, passive immunity is developed when you receive antibodies from another person.
no
They took dead cow pox virus and injected it into humans . This developed an immunity in the host.
Their immune systems aren't as developed as adults' are. Babies are born with some natural immunity passed down from the mother, but for the most part we humans have to earn our badges of immunity by having the disease first.
innate
false
Active immunity involves the production of antibodies (by B lymphocytes) and cell-mediated response (with T lymphocytes). It renders relatively longer immunity (compared to passive immunity). Active immunity may be natural or artificial.This type of active immunity is said to be natural because the immunity is induced not by deliberate exposure (such as vaccination). The individual has developed immunity to a live pathogen by having been exposed to it and by developing a primary immune response that led to immunological memory.
