| Attribute | Innate Immunity |
|---|---|
| Response Time | Fast: minutes or hours |
| Specificity | Only specific for molecules and molecular patterns associated with general pathogens or foreign particles |
How long does passive immunity last?
The exact amount of protection that a baby receives from its mother depends on the antibodies that the mother has in her immune system. Research indicates that a baby’s passive immunity lasts for around six months.
How long does active immunity and passive immunity last?

| Active Immunity | Passive Immunity | |
|---|---|---|
| Takes effect | Over time (typically several weeks) | Immediately |
| Length of efficacy | Long-term to lifelong | Short-term |
What is the difference between passive and active immunity?
Two types of immunity exist — active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.
What is the difference between active and passive immunity?
Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.
How long does artificial active immunity last?
It can take days or weeks after the first exposure for active immunity to develop. But once it does so, the protection can last an entire lifetime. Active immunity can occur in one of two ways: naturally or via an immunization.
