Is active immunity the same as acquired?
Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.
Is active immunity the same as innate immunity?
When you are immune to a disease, your immune system can fight off infection from it. Immunity is either innate or adaptive. Innate immunity, also known as natural or genetic immunity, is immunity that an organism is born with….Active vs passive immunity.

Is passive immunity the same as acquired?
Passive immunity provides immediate protection, but the body does not develop memory; therefore, the patient is at risk of being infected by the same pathogen later unless they acquire active immunity or vaccination.
What is the difference between active immunity 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.
What do you mean by passive immunity?
Passive immunity: Immunity produced by the transfer to one person of antibodies that were produced by another person. Protection from passive immunity diminishes in a relatively short time, usually a few weeks or months.
What is artificially acquired active immunity?
Artificially acquired active immunity is protection produced by intentional exposure of a person to antigens in a vaccine, so as to produce an active and lasting immune response.
What is an example of active immunity?
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 is actively acquired immunity?
Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response.
What is acquired or adaptive immunity?
Acquired (adaptive or specific) immunity is not present at birth. It is learned. The learning process starts when a person’s immune system encounters foreign invaders and recognizes nonself substances (antigens).
What are the two types of innate immunity?
The immune system is complex and is divided in two categories: i) the innate or nonspecific immunity, which consists of the activation and participation of preexistent mechanisms including the natural barriers (skin and mucosa) and secretions; and ii) the adaptive or specific immunity, which is targeted against a …
