vaccines monoclonal antibodies
Overview
This lesson explores the principles behind vaccines and monoclonal antibodies, two crucial biotechnological tools in medicine. We will delve into how these agents manipulate the immune system to provide protection against diseases or target specific molecules for therapeutic purposes. Understanding their mechanisms is vital for appreciating modern disease control and treatment strategies.
Vaccines: Principles and Types
Vaccines work by exposing the immune system to antigens from a pathogen without causing the disease itself. This stimulates the production of memory B cells and T cells, providing long-term immunity. When the vaccinated individual encounters the actual pathogen, their immune system can mount a rapid...

Key Concepts
- Vaccination: The process of introducing weakened or inactivated pathogens, or their components, into the body to stimulate an immune response and confer immunity.
- Active Immunity: Immunity developed by an individual's own immune system in response to exposure to an antigen, either naturally or through vaccination.
- Passive Immunity: Immunity acquired from an external source, such as antibodies passed from mother to child or through antibody injections.
- Antigen: A substance that can stimulate an immune response, typically a protein or polysaccharide on the surface of a pathogen.

Exam Tips
- →Distinguish clearly between active and passive immunity, providing examples for each. Remember that vaccines induce active immunity.
- →Be able to describe the process of monoclonal antibody production (hybridoma technology) in detail, including the purpose of each step and the role of HAT medium.
