Adjuvants

enhance the immune response to a vaccine

Preservatives

prevent bacterial or fungal contamination of vaccine

Additives

stabilize vaccines from adverse conditions such as freeze-drying or heat, thereby maintaining a vaccine's potency

Aluminum hydroxide

MILDEST ADJUVANT

The reaction is there but is not very visible and will disappear over a short period of time.

Water based adjuvant

MORE "POWERFUL" ADJUVANT

*Create a bigger and longer lasting reaction than aluminum hydroxide.

*Give a very high antibody response that will last for 6 months after only one initial vaccination.

Oil adjuvants

MOST AGGRESSIVE ADJUVANT

Least desirable due to substantial "lumps" created and the length of time they persist

Antigen, Carrier/Vehicle, Adjuvant, Preservatives, Buffer system

What are the 5 vaccine components

Live Virus Vaccine

a biological product that contains a modified live virus (MLV), also called an attenuated virus.

Killed Virus Vaccine

type of product contains virus particles that are inactivated and unable to replicate in the vaccinated animal. These products usually contain adjuvant, which enhance the immune response

Bacterins

any product containing inactivated bacteria and their growth products

Toxoid

product produced by inactivating the exotoxins of certain bacteria. These products are cell free and generate an antitoxin response in animal

Bacterin/Toxoid

a combination of two different biological products. Each fraction generates a particular response by the animal's defense mechanism, namely antibody and antitoxin responses.

Live Bacterial Vaccine

may be called a live avirulent culture vaccine. This product contains organisms that are nonpathogenic for target animals.

Sub-unit Vaccines

these products contain bacterial or viral extract. The extracts are the important antigenic portions of the disease causing organism.

Autogenous Vaccines

vaccines made from bacteria isolated from a specific farm and used only on that far,. They are not products generated from standard cultures and are usually used before commercial vaccines are available.

*Induce inflammation at the site of vaccination

*May cause local irritation and swelling at site of vaccination

Disease

any deviation from the normal health which temporarily impairs vital functions.

Farm Biosecurity

measures imposed to protect a biological system from attack by potentially harmful microorganisms that can reduce the level of health of man and animals

Disease Control in Host

provide proper nutrition to enhance animal resistance to disease or by selecting breeds, which are more resistant to diseases

Disease Control in Agent

proper use of biologicals, antimicrobials and disinfectants

Disease Control in Environment

properly designed housing structure and farm lay out (e.g. ventilation)

Equilibrium

Host and agent must be in a state of _____________ with the environment acting as a balancer.

False

True or False.

Any disturbance in this balance of relationship between host and agent will not lead to disease

True

True or False.

Much attention is concentrated on the causative agents of the disease themselves leading to an over reliance on biologicals and antimicrobials.

Host, Environment

It has to be emphasized that two other components of the health triad, namely ____ and ___________ share equal importance in the causation of the disease.
