Question

difference Serum and vaccine ( preparation)​

Answer 1

Answer:

Serum and vaccines differ in how they prevent infection. Serum is defined as, “an amber-colored, protein-rich liquid that separates out when blood coagulates. The blood serum of an animal, used especially to provide immunity to a pathogen or toxin by inoculation or as a diagnostic agent”. A vaccine is defined as, “a substance used to stimulate the production of antibodies and provide immunity against one or several diseases, prepared from the causative agent of a disease, its products, or a synthetic substitute, treated to act as an antigen without inducing the disease.

Serum is a naturally occurring substance in the blood. It is made up of antibodies and tissue fluid. Antibodies are proteins in the body that help to either neutralize or induce an immune response to bacteria, viruses and foreign bodies (antigens) that are introduced into the body. For example, if someone is exposed to a certain strain of the influenza virus, their sera (plural of serum) will contain antibodies to that strain, that will help the body fight the virus and heal the individual.

A vaccine is made up of the either: (1) the actual virus/bacteria that is weakened or inactivated so as not to cause disease; (2) a pieces of the virus, or, (3) lab-derived (man made) that look similar to parts of the bacteria/virus. Vaccines actively cause the body to mount an immune response, (create appropriate protective serum), to protect against possible infection.

So I’m essence, the difference between serum and a vaccine is that , a vaccine teaches your immune system how to fight an infection. Serum either neutralizes the "infection" or stimulates your immune system to attack an infection. Vaccines are generally prophylactic where as antiserums are generally a form of treatment.
