Study Notes
What is a Vaccine?
- A biological preparation that provides active acquired immunity to a particular infectious disease.
- Contains an agent resembling a weakened or killed form of the pathogen.
- Agents can be:
- Toxins produced by the microbe
- Surface proteins of the microbe
- Nucleic acid of the microbe coding for toxins or surface proteins
How Vaccines Work
- The agent stimulates the body's immune system.
- Immune system recognizes the agent as a threat.
- Immune system destroys the agent and develops the ability to recognize and destroy future encounters of the same microorganisms.
Immune Response:
- Infections can trigger inflammatory responses.
- White blood cells are recruited to the site of infection.
- Cytotoxic T-cells eliminate pathogen-infected cells.
- B-cells neutralize circulating viruses.
Vaccination
- Stimulates an immune response against infectious microorganisms.
- Provides protection against future infections.
- Targets viruses, bacteria, and toxins.
Vaccination Outcomes
- Develops long-term protective immune memory.
- Prevents future infections.
