what is the relationship between vaccination and immunity?
236960
Vaccines stimulate the body's own immune system to protect the person against subsequent infection or disease." A person becomes immune to a disease when the body has been exposed to it either through illness or vaccination. The immune system develops antibodies to the disease so that it cannot make you sick again.

The immune system is the complex collection of cells and organs that destroys or neutralizes pathogens that would otherwise cause disease or death. The lymphatic system, for most people, is associated with the immune system to such a degree that the two systems are virtually indistinguishable.

INNATE IMMUNITY. Innate, or nonspecific, immunity is the defense system with which you were born. It protects you against all antigens. Innate immunity involves barriers that keep harmful materials from entering your body. These barriers form the first line of defense in the immune response.

Humoral immunity refers to antibody production and the accessory processes that accompany it, including: Th2 activation and cytokine production, germinal center formation and isotype switching, affinity maturation and memory cell generation.

Innate immunity refers to nonspecific defense mechanisms that come into play immediately or within hours of an antigen's appearance in the body. These mechanisms include physical barriers such as skin, chemicals in the blood, and immune system cells that attack foreign cells in the body.

The humoral immunity is associated with the B-lymphocytes and is responsible for destroying the pathogens by producing antibodies against it, whereas the cell-mediated immunity is associated with the T-lymphocytes and is responsible for the destroying the pathogens or microorganism which have invaded the cells without ...

Humoral immunity can be subdivided into active and passive immunity. In active immunity the person actively makes an antibody after exposure to a foreign antigen. ... In passive immunity a person is given an antibody that has been made by someone else.

2 Which of the following is NOT a vaccine-preventable disease? Immunization prevents illness, disability and death from vaccine-preventable diseases including cervical cancer, diphtheria, hepatitis B, measles, mumps, pertussis (whooping cough), pneumonia, polio, rotavirus diarrhoea, rubella and tetanus.

Immunogen is a stimulus that produces a humoral or cell-mediated immune response, whereas antigens are any substance that binds specifically to an antibody or a T-cell receptor.

Because the bacteria in the vaccine is weak, it triggers the immune system to protect against the disease. This gives good immunity to people who receive it without actually causing the disease. The vaccine is 70 to 80% effective against the most severe forms of TB, such as TB meningitis in children.

What Is Immunization? Immunization, also known as multi-period immunization, is a risk-mitigation strategy that matches the duration of assets and liabilities, minimizing the impact of interest rates on net worth over time.

Passive Immunity. Passive immunity is provided when a person is given antibodies to a disease rather than producing them through his or her own immune system. ... This is the major advantage to passive immunity; protection is immediate, whereas active immunity takes time (usually several weeks) to develop.

Shots protect your cat from diseases caused by viruses and bacteria. They can also strengthen her immune system. Whether you have a kitten or an adult cat, your vet can help you figure out which vaccines are best and how often your kitty should get shots.

An attenuated vaccine is a vaccine created by reducing the virulence of a pathogen, but still keeping it viable (or "live"). Attenuation takes an infectious agent and alters it so that it becomes harmless or less virulent. These vaccines contrast to those produced by "killing" the virus (inactivated vaccine).

Immunity: Natural immunity occurs through contact with a disease causing agent, when the contact was not deliberate, where as artificial immunity develops only through deliberate actions of exposure. ... This vaccine stimulates a primary response against the antigen in the recipient without causing symptoms of the disease.
