Found in high concentrations in the mucous membranes as well as in saliva and tears (Classes of immunoglobulins)
IgA
Exists in small amounts in the blood; is the least understood antibody (Classes of immunoglobulins)
IgD
Is the most abundant type of immunoglobulin; is found in all body fluids and protects against bacterial and viral infections (Classes of immunoglobulins)
IgG
Associated mainly with allergic reactions; is found in the lungs, skin, and mucous membranes (Classes of immunoglobulins)
IgE
Refers to blood serum containing polyclonal antibodies and is used to pass on passive immunity to many diseases
Antiserum (plural: antisera)

Virulent pathogenic organisms have lost their capacity to induce full-blown disease but retain their immunogenicity (Types of vaccines)
Live attenuated (avirulent) vaccines
Made by killing the disease-causing microbe with chemicals, heat, or radiation (Types of vaccines)
Inactivated (killed) vaccines
Used when a bacterial toxin is the main cause of illness (Types of vaccines)
