Inactivated vaccines:  are made from organisms that are killed during the manufacturing process. Examples include pertussis and cholera vaccines. These vaccines can't cause the disease they're meant to prevent, but still trigger an immune response.

Toxoids: are vaccines produced from bacterial toxins that have been rendered harmless through heat or formalin treatment. Examples include diphtheria and tetanus vaccines. Toxoids work by stimulating the body to produce antibodies that can neutralize the toxins.

Vaccination: is the process of giving a vaccine or inoculating antigenic material to produce active artificial immunity. This helps the body's immune system recognize and fight specific diseases, providing protection against future infections.


RESISTANCE OF THE NEW HOST

Immunity has been defined as the resistance of a new host to infection, whereas, resistance is the ability of the body to withstand infection.

Resistance is the defense mechanism, which is called into interplay after invasion has occurred and which enables the body to kill off the invader and combat its ill effects.

Resistance is the sum total barriers to the progress of invasion and the        multiplication of infectious agents or damage by their toxic products. If the body’s defense mechanism is sufficiently great the term “IMMUNITY” is used. There is no absolute immunity against all circumstances and degree of exposure, but the term “IMMUNITY” refers to the possession of sufficient resistance which protects a person against the average infectious dose of infection.                                  


TYPES OF IMMUNITY OR THE NATURE OF RESISTANCE

The nature of resistance is not clearly understood. However, resistance is a property of a body which enables it to ward off the invasion of pathogenic organisms. To activate this, the factors of resistance are classified as specific and non – specific immunity or mechanism.


TYPES OF IMMUNITY

1- Specific immunity.

2- Non specific immunity.

 

1. SPECIFIC IMMUNITY​

Specific or acquired immunity is the one that can be acquired either naturally or artificially and both could be acquired passively or actively.
