1. ANTIGEN ANTIBODY Proteins that recognize and bind to antigens.
A protein on a foreign object that stimulates the immune system to produce antibodies.
A virus, bacteria, toxin, ... that trigger the immune response.

3. How can the immunity be acquired?
The injection of a weakened form of a pathogen, dead pathogens, or parts of pathogens to produce immunity is known as vaccination.
The immune system recognizes these
pathogens as antigens, and creates
millions of plasma cells ready to produce
specific types of antibodies.
When the real virus or bacteria infect the
body, the immune system responds rapidly
creating enough amounts of antibodies to
destroy the pathogens. That is why the
body does not get sick.

4. 8) Vaccinations play a major role in medicine today
8) Vaccinations play a major role in medicine today. Explain the role of vaccines in the prevention of disease. Your answer must include at least: a) a description of the contents of a vaccine b) a description of how a vaccine protects the body from disease c) one specific reason certain vaccinations are required for students to attend public schools
A vaccine contains weakened , altered or dead microbes
A vaccine stimulates the immune system to react and
produce antibodies and memory T cells. In the future, the immune system will “remember” how to make antibodies
against a specific antigen.
To keep school children protect from a disease
To prevent the spread of disease
To prevent an epidemic in school

5. Discuss the use of antibiotics and vaccines in the treatment and prevention of bacterial diseases. In your answer be sure to include:   a) what is in a vaccine b) how a vaccine promotes immunity c) one advantage of the use of vaccinations to fight bacterial diseases d) one disadvantage of the use of antibiotics to fight bacterial diseases
A vaccine contains dead, or weakened microbes or parts of microbes
Exposures to the microbes stimulates production of antibodies and memory cells
Usually, you will not get the disease
Or vaccinations provide immunity that lasts a long time
Certain bacteria develop resistance to antibiotics. Therefore, antibiotics are useless in fighting off infectious diseases caused by these type of bacteria.
Allergies can be caused by antibiotics
Antibiotics may cause side effects in the body
