What is a Specific Immunity? Specific immunity is the body's learned immune response to disease-causing foreign substances, also referred to as pathogens or antigens. It is also commonly called acquired immunity or adaptive immunity.

- Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized. Once an antigen has been recognized, the adaptive immune system creates an army of immune cells specifically designed to attack that antigen.he adaptive immune response is more complex than the innate. The antigen first must be processed and recognized.

- Active immunity is stimulation of the immune system to produce antigen-specific humoral (antibody) and cellular immunity. Unlike passive immunity, which is temporary, active immunity usually lasts for many years, often for a lifetime.

Specific and Non-specific immune responses A non-specific immune response is where the immune response acts broadly against a range of pathogens to immobilize and destroy them without the production of antibodies. the first and second line defense systems form part of the non-specific immune response.

herd immunity herd immunity. a level of resistance in a herd or flock which is sufficient to prevent the entry of a particular disease into, or its spread within, the herd. The resistance may be innate, a genetically based resistance, or acquired as a result of previous exposure to the particular agent or of vaccination. level of resistance in a herd or flock which is sufficient to prevent the entry of a particular disease into, or its spread within, the herd.

Vaccine A vaccine is a biological preparation that provides active acquired immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing micro-organism and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.accination is the most effective method of preventing infectious diseases; widespread immunity due to vaccination is largely responsible for the worldwide eradication of smallpox and the restriction of diseases such as polio, measles, and tetanus from much of the world.

Lymphocytes? Cell-mediated immunity (CMI) is an immune response that does not involve antibodies but rather involves the activation of macrophages and NK-cells, the production of antigen-specific cytotoxic T-lymphocytes (def), and the release of various cytokines (def) in response to an antigen (def). Cellular immunity protects the body by: 1.

Difference between innate and adaptive immunity Also known as acquired immunity and specific immunity, adaptive immunity refers to instances when a person will not be affected by a certain microorganism because of the fact that this specific individual has been infected by that microorganism before.

Immunity (medical) 1 Artificially acquired passive immunity is a short-term immunization achieved by the transfer of antibodies, and can be administered in several forms.  Active immunity is long lasting immunity produced by the body's own immune system and involves the production of long lasting memory cells.

The Human Immune System and Infectious Disease Specific immunity is a complement to the function of phagocytes and other elements of the innate immune system. In contrast to innate immunity, specific immunity allows for a targeted response against a specific pathogen.on-Specific (Innate) Immunity. The human immune system has two levels of immunity: specific and non-specific immunity. Through non-specific immunity, also called innate immunity, the human body protects itself against foreign material that is perceived to be harmful.

Adaptive Immunity The adaptive immune or specific immune response consists of antibody responses and cell-mediated responses, which are carried out by different lymphocyte cells, B cells and T cells, respectively.ell-mediated immunity does not involve antibodies but rather involves the activation of macrophages, natural killer cells (NK), antigen-specific cytotoxic T-lymphocytes, and the release of various cytokines in response to an antigen.

Passive immunity Key Points. 1  Passive immunity is the transfer of active humoral immunity in the form of ready-made antibodies from one individual to another. 2  Naturally-acquired passive immunity includes antibodies given from the mother to her child during fetal development or through breast milk after birth.

Introduction to Immunology Tutorial Adaptive immunity refers to antigen-specific immune response. The adaptive immune response is more complex than the innate. The antigen first must be processed and recognized.

- Active immunity is stimulation of the immune system to produce antigen-specific humoral (antibody) and cellular immunity. Unlike passive immunity, which is temporary, active immunity usually lasts for many years, often for a lifetime. One way to acquire active immunity is to have the natural disease.nother way to produce active immunity is by vaccination. Vaccines interact with the immune system and often produce an immune response similar to that produced by the natural infection, but do not subject the recipient to the disease and its potential complications.

- Immunity to a disease is achieved through the presence of antibodies to that disease in a person’s system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific.

Immune Response Overview. One characteristic of specific immunity is recognition. Immune responses begin when the body recognizes the invader as foreign. This occurs because there are molecules on foreign cells that are different from molecules on the body's cells.ne characteristic of specific immunity is recognition.

- Active immunization. Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently.nswers: The production of antibodies against a specific agent by the immune system. Active immune can be acquired two ways, By contacting an infectious disease, such as chicken pox's (for example) or vaccination such as polio (for example).

The Human Immune System and Infectious Disease Two types of white blood cells called lymphocytes are vital to the specific immune response. Lymphocytes are produced in the bone marrow, and mature into one of several subtypes. The two most common are T cells and B cells. An antigen is a foreign material that triggers a response from T and B cells.The human body has B and T cells specific to millions of different antigens. We usually think of antigens as part of microbes, but antigens can be present in other settings.on-Specific (Innate) Immunity. The human immune system has two levels of immunity: specific and non-specific immunity. Through non-specific immunity, also called innate immunity, the human body protects itself against foreign material that is perceived to be harmful.

What is natural immunity? Natural immunity is the non-specific immunity that a person has. Basically, the body recognizes something as not self and it attacks it, no matter what it is. Acquired immun … ity is when you are exposed to a specific illness and the body attacks it and forms specific antibodies for that particular illness.ne of the major properties of a healthy and effective immune system is the ability to differentiate between self and non-self. Natural immunity confers that ability upon an infant to some degree, allowing his immune system to identify and fight threats.

Vaccine A vaccine can confer active immunity against a specific harmful agent by stimulating the immune system to attack the agent. Once stimulated by a vaccine, the antibody-producing cells, called B lymphocytes, remain sensitized and ready to respond to the agent should it ever gain entry to the body.
