Question

Why is it necessary to safety store the pathogens of the disease against which vaccines are to be produced

Answer 1

Answer:

The complexity of pathogenesis of hazardous pathogens varies from each one and day to day new pathways, new antigenic components of such pathogens are identified.

To face and meet new challenges thrown by these pathogens like which includes mutations in antigenic structures, or opting of this pathogen to a new host with an extended host range.

They need to be stored safely to study these things or it's potential use in developing biological technologies which may come into play in future which cannot be predicted.

Explanation:

Answer 2

Answer:

1. Now-a-days with thr advent of biotechnology, the vaccines are manufactured in laboratories with the help of bacteria. For this purpose, a detailed study of the diseases - causing germ is undertaken. The genes and the DNA of such microbes are which can act against such microbes are synthetically prepared in the laboratories. The safe vaccine is produced in such a way which can defend the body against infections.
2. Some types of vaccines are prepared from the extracts of germs. These germs or microbes are deactivated and made dormant. When they are injected in the body of a person, they imitate the defending action. The body of such vaccinated person, already develops the antibodies in his or her body. When in future, this person is agin attacked by similar germs the defence starts immediately and the person does not become sick.
