Passive immunity is the transfer of antibody produced by one human or other animal to another. Passive immunity provides protection against some infections, but this protection is temporary. The antibodies will degrade during a period of weeks to months, and the recipient will no longer be protected.
What are examples of natural immunity?
The body responds by making its own antibodies. There are two examples of passive naturally acquired immunity: The placental transfer of IgG from mother to fetus during pregnancy that generally lasts 4 to 6 months after birth; and The IgA and IgG found in human colostrum and milk of babies who are nursed.
Are we born with natural immunity?
Babies produce their own antibodies every time they are exposed to a virus or germ, but it takes time for this immunity to fully develop. The passive immunity passed on from the mother at birth also doesn’t last long and will start to decrease in the first few weeks and months after birth.
What are the types of immunity?

What are the two types of active immunity?
There are two types of immunity: innate and adaptive.
How do we acquire immunity?
Immunity can be acquired either actively or passively. Immunity is acquired actively when a person is exposed to foreign substances and the immune system responds. Passive immunity is when antibodies are transferred from one host to another.
What is immunity and immune system?
Summary. The immune system is a complex network of cells and proteins that defends the body against infection. The immune system keeps a record of every germ (microbe) it has ever defeated so it can recognise and destroy the microbe quickly if it enters the body again.
What are examples of active immunity?
Active immunization stimulates the immune system to produce antibodies against a particular infectious agent. Active immunity can arise naturally, as when someone is exposed to a pathogen. For example, an individual who recovers from a first case of the measles is immune to further infection…
What are examples of passive immunity?
Passive immunity can occur naturally, such as when an infant receives a mother’s antibodies through the placenta or breast milk, or artificially, such as when a person receives antibodies in the form of an injection (gamma globulin injection).
At what age is your immune system the strongest?

Both natural and artificial immunity can be further subdivided, depending on the amount of time the protection lasts.
