What type of immunity is used for illness prevention?
Passive Immunity - antibodies given to a person to prevent disease or to treat disease after the body is exposed to an antigen.
How do you get disease specific immunity?
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.
What is chemoprophylaxis treatment?

Antibiotics, for example, may be administered to patients with disorders of immune system function to prevent bacterial infections (particularly opportunistic infection).
What is an example of specific immunity?
An example is the neutralizing epitope of polioviruses (D antigen) that requires the intact capsid to elicit neutralizing antibodies. The protective protein antigens are highly specific and are unique to each pathogen.
What are the 4 types of immunity?

What is specific specific immunity?
Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its hallmarks are its ability to learn, adapt, and remember. Acquired immunity takes time to develop after first exposure to a new antigen.
What is immune specificity?
Specificity defines another dimension of immune recognition. Specificity is the degree to which an immune response discriminates between antigenic variants. A simple approach measures the relative binding affinities of purified antibodies or T cell receptors for different antigens.
What is specific immunity quizlet?
